Phosphofructokinase is an allosteric enzyme that catalyzes the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate,

an early step of glycolysis. An increased accumulation of ATP (an allosteric regulator of PFK) would be expected to...

b activate the enzyme and slow the rates of glycolysis and the citric acid cycle.
c. inhibit the enzyme and thus increase the rates of glycolysis and the citric acid cycle.
d. activate the enzyme and increase the rates of glycolysis and the citric acid cycle.

Answer:

The correct answer is a Inhibit the enzyme and slow the rates of Glycolysis and citric acid cycle.

Explanation:

ATP accumulation result in blocking the activity of the rate limiting enzyme  of glycolysis  Phosphofructokinase that catalyses the conversion of fructose-6-phosphate to fructose -1,6-bisphosphate .

            ATP is an Allosteric inhibitor of Phosphofructokinase enzyme and this enzymatic inhibition decreases the rate of glycolysis and as the rate of glycolysis decreases the rate of TCA cycle is also decreased because TCA cycle  depends on glycolytic end product Pyruvate. As glycolysis rate is decreased pyruvate is not formed in a sufficient amount to carry out its conversion to Acetyl CoA  and enters into TCA Cycle.

Match each cellular defense with the infection it would most likely target.
Fynjy0 [20]

Answer:

(A) Natural killer- virus-infected cell.

(C) Neutrophil - bacteria in skin lesion.

(B) Eosinophil -  tapeworm in the intestines.

Explanation:

<u>Natural killer cells</u> are a type of the cytotoxic lymphocyte that are critical to the innate immune system. NK cells are the cells which provide rapid responses to the <u>virus-infected cells</u>.

<u>Neutrophils</u> are type of the phagocyte which are found in bloodstream. During beginning of the acute phase of inflammation particularly which are a result of the <u>bacterial infection</u>, neutrophils are the first-responders of the inflammatory cells to migrate towards inflammation's site.

<u>Eosinophils</u> are variety of the white blood cells which are responsible for combating <u>parasites</u> and also certain infections. Thus it will mostly target <u>tapeworm in the intestine</u>.

Which of the following is not responsible for driving deep ocean circulation?
Deffense [45]

Answer:

Winds

Explanation:

Winds only act on oceans surfaces. The winds move the upper layers of ocean waters due to drag as they blow in the atmosphere. They are the reason for waves. However, the effects of winds cannot be felt in deep oceans where much of the movement is dependent on variable densities of ocean currents (due to differences in temperatures and salinity levels).

Blood vessel with the largest lumen​
ivann1987 [24]

A vein is a blood vessel that conducts blood toward the heart. Compared to arteries, veins are thin-walled vessels with large and irregular lumens.

<h3>Where are blood vessels found in your body?</h3>

  • Blood is delivered to human tissues by arteries, which act as conduits or channels. Two tube-like closed systems comprised of the vessels start and stop at the heart. Blood is transported from the right ventricle to the lungs and back to the left atrium by one system, the pulmonary arteries.
  • Your circulatory system is made up of blood vessels and heart vessels. About 60,000 miles of blood arteries make up your body.
  • Blood is carried through blood arteries throughout the body. Blood is carried away from the heart through arteries. The blood is brought back to the heart by veins. Body cells and tissues are surrounded by capillaries that transport and absorb nutrition, oxygen, and other chemicals.
  • Blood vessels are the channels or conduits through which blood is distributed to body tissues.
  • The arteries (red) carry oxygen and nutrients away from your heart to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues.
