Unlike skeletal muscle, the muscle cells of the heart (called "cardiomyocytes") metabolize very little glucose, relying almost exclusively on metabolism of fatty acids for their energy. Which of the following statements are likely to be true of cardiomyocytes, but NOT skeletal myocytes? (select two answers)

a. low levels of glycogen storage, even when blood glucose is high
b. high levels of glycogen storage, even when blood glucose is low
c. low lactate production, even at high activity
d. high lactate production, even at low activity
e. many mitochondria compared to other cells
f. few mitochondria compared to other cells

Answers

Answer 1

Answer: A. low levels of glycogen storage, even when blood glucose is high.

C. low lactate production, even at high activity.

Explanation:

Cardiomyocytes are also known as the myocardiocytes. They are the cells which makes up make up the muscle if the heart. They're responsible for the generation of the contractile force in the heart which helps in the pumping if blood.

From the options given, the statements that are likely to be true of cardiomyocytes, but not of skeletal myocytes include:

• low levels of glycogen storage, even when blood glucose is high.

• low lactate production, even at high activity.

Answer 2

Answer:

The answer is A and C

Explanation:

Since cardiomyocytes are dependent on fatty acids, they rely on oxidative phosphorylation to generate energy, and consume very little glucose. Due to this, they have very low need for fermentation of pyruvate. In fact, they can absorb lactate generated by skeletal myocytes and erythrocytes and oxidize it for additional energy. Another consequence of this metabolism is that cardiomyocytes store little or no glucose as glycogen.

Skeletal myocytes and cardiomyocytes both have high energy needs and thus have more mitochondria than other cells. Cardiomyocytes have an even greater density of mitochondria than skeletal myocytes because they depend almost entirely on oxidative phosphorylation for their energy needs. This dependence on oxidative phosphorylation also explains the extraordinary sensitivity of cardiac muscle to hypoxic (low-oxygen) events. Without oxygen, cardiomyocytes rapidly run out of energy and can quickly die.

Eutrophication occurs when excess nutrients are supplied to a region, leading to an algae bloom and ultimately ______
A. Coral bleaching
B. Ocean deoxygenation
C. Ocean acidification
D. Overfishing

Answers

Answer:

The correct answer is - B. Ocean deoxygenation.

Explanation:

Eutrophication is the process in which a water body gets excessively rich in nutrients that leads to the algal growth or plankton growth in this region and covers the complete surface or most of the water body.

Due to this algal and plankton growth, there is a significant decrease in the concentration of the dissolved oxygen in water bodies that result in the incapability of supporting the lives found in it. The primary and main reason for this deoxygenation is eutrophication. Ocean deoxygenation is the reduction of the oxygen concentration of the oceans.

Hydrocarbons are burned to produce water and carbon dioxide. Propane (C3H8) is a homologous series alkane that belongs to the hydrocarbon family. As a result, when propane is burned, three molecules of carbon dioxide and four molecules of water are produced.

Because there is an overabundance of oxygen, carbon dioxide is created when butane is completely burned.

Which of the following statements relating to leptin and the metabolism of lipids is correct. (Select all that apply.) Leptin acts mainly in the brain to stimulate appetite. High levels of leptin are interpreted as overfeeding. Insulin stimulates production of leptin in adipocytes. Leptin is a hormone involved in short-term control of eating behaviour. Higher leptin levels result in a decrease in appetite.

Answers

Answer:

High levels of leptin are interpreted as overfeeding.

Insulin stimulates production of leptin in adipocytes.  

Higher leptin levels result in a decrease in appetite.

Explanation:

Leptin is a peptide hormone that helps to control body weight. This hormone (leptin) is synthesized by fat cells (i.e., adipocytes), then circulates in the blood and goes to the brain, in particular in a region of the brain called the hypothalamus, where it acts to alter food intake over the long term. Higher leptin levels trigger the hypothalamus to lower the appetite. Insulin is another peptide hormone that acts to regulate long-term leptin secretion of adipose cells through a posttranscriptional mechanism. In turn, leptin increases insulin sensitivity, thereby both hormones regulate each other. When body fat decreases as a consequence of decreased appetite, insulin and leptin concentrations in the bloodstream also decrease.

A biologist discovered a new animal. Upon studying its embryonic development, she observed radial cleavage with the blastopore developing into an anus. This animal was categorized as a parazoan. pseudocoelomate. deuterostome. protostome. radiata.

Answers

Answer:

The correct answer is ''deuterostome''.

Explanation:

Deuterostomes are a superphylum of animals in which the anus is formed in or near the blastopore area in the developing embryo, and the mouth is secondarily formed elsewhere. The oral apparatus that these adult animals enjoy does not come from the embryo's blastopore. Instead it is a new formation. They enter the Bilateria classification, where species that enjoy bilateral symmetry are incorporated. In deuterostomes, the primary phases of division occur in parallel to the axis between the tips. That is, the segmentation they have is radial when the embryo is in state 1 with four cells.

An enzyme, Pittpantherase, has a KM of 8mM. At a substrate concentration of 4mM, the velocity of the reaction was 2mM/min. What is Vmax for this enzyme

Answers

Answer: [Vmax]= 6mM/min.

Explanation:

Enzymes are proteins that produce a specific chemical change in a substance, called substrate, resulting in a product. By following the rate of product appearance (or disappearance of the substrate) as a function of time, the kinetics of the reaction is obtained. As the reaction proceeds, the rate of product formation decreases and the substrate is consumed.

The rate [V] indicates the amount of substrate that is converted into product per second. With increasing substrate concentrations [S], the enzyme approaches its maximum velocity [Vmax], but does not reach it. For this reason, there is no specific value of [S] for Vmax. However, a characteristic parameter of the enzyme can be defined using the substrate concentration at which half of the maximum velocity (Vmax/2) is reached. The initial velocity of the reaction is equal to the slope of the zero-time forward curve and is measured before 10% of the total substrate is consumed, so that the substrate concentration can be considered as essentially constant throughout the experiment. So, although it is impossible to measure exactly the substrate concentration that gives Vmax, enzymes can be characterized by the substrate concentration at which the reaction rate is half the maximum rate. This substrate concentration is known as the Michaelis-Menten constant (KM). For enzymes exhibiting simple Michaelis-Menten kinetics this constant represents the dissociation constant of the enzyme-substrate complex (or the inverse of the enzyme-substrate affinity). Thus, Km indicates the affinity of the enzyme for its substrate, since the higher the Km the lower the affinity. And the lower the Km the higher the affinity.

The formula for the calculation is as follows:

[tex]V_{0}= \frac{[Vmax] x [S]}{[S]+[KM]}[/tex]

So if we replace the numbers, we get:

[tex]2mM/min= \frac{[Vmax] x [4mM]}{[4mM]+[8mM]}[/tex]

If we clear the equation, we obtain that [Vmax]= 6mM/min.

Psychometric scores for anxiety, depression, negative self, somatization, and hostility were combined into a single Global Severity Index (GSI). Global Severity Index was compared for 80 adolescents who were seen in the outpatient clinic for 7 different physical complaints (short stature, obesity, lack of weight gain, breast problems, genital problems, menstrual problems, and hirsutism). Report the degrees of freedom for the relevant F statistic in the numerator and the denominator. (Round your answers to the nearest whole number.)

Answers

Answer:

The correct answer is -

Numerator = 6

Denominator = 73

Explanation:

In F static test or table there are two sets of degrees of freedom: one for the numerator and one for the denominator. The degrees of freedom are equal to the number of observations minus one. Thus, if the sample size were 7 then the degree of freedom would be 7 minus 1

Numerator df = 7 - 1 = 6

Thus, the numerato would be - 6.

Denominator is calculated by subtracting the observation or variables from the total number of sample size.

Denominator df = 80- 7 = 73

Assuming that you observed similar patchy bacterial growth pattern in plates "B-Amp, phage" and "C-LB, phage". The T4 phages greatly affected the growth of E. coli strain CR63 in the LB plate ("C-LB, phage" plate), creating a patchy bacterial growth pattern similar to the expected result in the ampicillin plate of strain BE with phage ("B-Amp, phage" plate). Besides experimental errors, describe the possible reasons why the bacterial colonies were isolated in these two plates. "B-Amp, phage" Plate (strain BE)?

Answers

Answer:

Some bacterias show a great resistance power to fight against T4 phages That leads to great growth in the medium given that resistance power may be given by plasmids As plasmids show the resistant genes that great work in the medium.

T4 phage is a virus that shows a lytic cycle after affecting bacteria and going to kill the bacterial cells in bacterial strain So no growth in LB media. Some bacteria are sensitive due to the lack of resistant genes therefore, their growth may affect by many factors of the medium. If the bacteria are recombinant, they show greater growth in the medium.

* B-Amp, Phage plate (strain Be), there is ampicillin, so inhibits the growth of bacteria but still there is patchy growth of bacteria and they still show the growth but due to presence of phage T4, they show patchy growth.

Answers

Answer:

During the conversion of glucose to pyruvate glycolysis or during the conversion of pyruvate to alcohol

Explanation:

During the conversion of glucose to pyruvate, NAD+ is converted into NADH.

What is alcoholic fermentation?

Alcoholic fermentation is a biological process that converts sugars into cellular energy while emitting ethanol and carbon dioxide as byproducts.

The NADH + H+ from glycolysis would be recycled back to NAD+ during the fermentation process, allowing glycolysis to continue. NAD+ is reduced during glycolysis to form NADH + H+.

Thus, during this, when glucose is converted to pyruvate, NAD+ is being converted to NADH.
