Question

1) which choice would be affected if the body did not produce CCK?

a)there would be a sharp increase in protein catabolism.

b)there would be little if any, fat emulsification

c)Chief cells would not produce HCl

D)swallowing would be painful

2) What action below would be affected if the body did not produce hydrochloric acid?

a) fat emulsification

b)carbohydrate digestion

c)protein digestion

d) segementation

Answer 1

1) b)there would be little if any, fat emulsification

Explanation: Cholecystokinin facilitates the digestion within the small intestine. It is secreted from mucosal epithelial cells in the first segment of the small intestine (duodenum).

It stimulates delivery into the small intestine of digestive enzymes from the pancreas and bile from the gallbladder.

If CCK is not produced, then bile will not be secreted from the gallbladder leading to inability to emulsify the fats and hence fat emulsification won't happen.

2) C) protein digestion

Explanation: HCl is required to activate the pepsinogen into pepsin to cause protein digestion. Hence deficinecy of HCl would result in would affect protein digestion
