What happens to pepsin when it leaves its
den301095 [7]

Explanation:

Since enzymes are proteinous in nature, they perform best at a particular physiological temperature, pH and location.

So, once pepsin gets transferred to duodenum (where trypsin) is located, it becomes inactivated because it functions best in the acidic medium of gastric gland, whereas pancreas has an alkaline medium.

Thus, alkaline pH of the duodenum will coagulate and inactivate pepsin.

JulsSmile [24]

Answer:

B. 3

Mitosis is the process of reproduction of somatic/body cells. This means that the number of chromosomes the original (parent) cell started out with, will remain the same for the daughter cells.

Given that if a parent cell has 3 chromosomes before mitosis, then the 2 daughter cells produced will also have 3 chromosomes after mitosis and cytokinesis.
