aldosterone.
glucagon.
insulin.
somatostatin.
cortisol.
2. the skeletal muscle fibers that would produce the highest concentration of pyruvate would be:
Fast glycolytic muscle fibers
none of the options are correct.
Slow oxidative muscle fibers
equally for slow oxidative and fast glycolytic muscle fibers.
Fast oxidative-glycolytic muscle fiber
3. The first heart sound occurs when the AV valves close; thus it marks?
The end of the ejection period
The beginning of the ejection period
Two of the choices are correct
The beginning of systole
The beginning of isovolumetric contraction
4. A new cardiovascular drug works to: (a) increase the pressure gradient in a blood vessel and (b) increase the length of the vessel. The effect on blood flow is to:
Both increase the blood flow
None of the choices are correct
Decrease the blood flow and increase the blood flow
Increase the blood flow and decrease the blood flow
Both decrease the blood flow
5. The AIDS virus selectively attacks:
helper T cells
memory B cells
both cytotoxic T cells and memory B cells
both cytotoxic T cells and helper T cells
cytotoxic T cells
Explanation / Answer
Ans. 1.
The choice is INSULIN.
Insulin converts glucose into glycogen thereby it will bring blood sugar levels down.
Ans. 2.
The choice is: Fast glycolytic muscle fibres.
These muscles uses anaerobic glycolysis and produces pyruvate which immediately gets converted into Lactic acid. Fast glycolytic muscle fibres fatigue very fast because of above reason.
Ans. 3.
The choice is: The beginning of systole.
Ans. 4.
The choice is: Increase the blood flow and decrease the blood flow.
Increase pressure gradient will increase the blood flow whereas increase length of vessel will decrease the blood flow.
Ans.5.
The choice is: Helper T cells.
AIDS virus attacks Helper T cells.
