Question

1. You have a patient that is hyperventilating and has a blood sugar level of 800 mg/dl (normal values = 100 mg/dl), what hormone should be injected for treatment?

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.
