Question

1.

Which of the following enzymes are normally stored as inactive zymogens?

Amylase

Secretin

Lipase

Nuclease

Pepsin

2.

Individuals that have a genetic condition where they lack bile salt production would:

All of the choices are correct

Two of the choices are correct

Not be able to add a polar head to the lipid for lipase digestion

Not be able to produce micelles and absorb fat

Not be able to complete carbohydrate digestion

3.

If an individual had damaged their medulla oblongata, what would be altered with their digestive system?

The production of HCl for the stomach would prevent enzyme activation

The swallowing reflex would be damaged and food would not travel down the esophagus

The enteric nervous system would prevent movement of digested materials along the tract

There would be no damage

The production of bile salts would prevent micelle production

4.

After drinking a fruit smoothie, most of the water and solutes will be reabsorbed in the:

Distal tubule

Collecting duct

Descending limb of the loop of Henle

Ascending limb of the loop of Henle

Proximal tubule

5.

What statement is false about atrial natriuretic peptide (ANP)?

It inhibits Na+ reabsorption in the distal part of the nephron

None of the statements are correct

It is released from the cardiac atria when the ECF volume is decreased

It inhibits aldosterone secretion by the adrenal cortex

It inhibits sympathetic nervous activity to the heart and blood vessels

6.

Which absorptive process occurs?

None of the choices are correct

All of the choices are correct

Monoglycerides (fat) is absorbed by active transport and enters the lacteal (lymph)

Water-soluble vitamins are carried out by micelles

Glucose (carbohydrate) is absorbed by active transport and enters the blood

7.

With a peptic (gastric) ulcer:

These are usually caused by bacterial infections and can compromise the mucosal barrier and stomach wall

These can be caused by excessive neural stimulation

These are usually caused by bacterial infections

These can be caused by excessive neural stimulation , re usually caused by bacterial infections and can compromise the mucosal barrier and stomach wall

These can compromise the mucosal barrier and stomach wall

Explanation / Answer

Ans-4- Proximal tubule . because 70% of tubular reabsorption occurs in PCT alongwith solutes including sodium,water is also re absorbed because water follows sodium and is reabsorbed quickly and mostly in pct.
