Answer:
b.Breaking of protein into peptides
Explanation:
The acid in the stomach causes food proteins to unfold in a process called denaturation. Denaturation exposes the protein's molecular bonds so that pepsin can access them and break the proteins into smaller fragments, called peptides or polypeptides.

Answer:
If pepsin is lacking in gastric juice, then the event in the stomach which will be affected is the breaking of proteins into peptides.
Explanation:
- In the mouth the food is mixed with the saliva of salivary glands and these glands contain the digestive enzyme ptyalin (an α-amylase). This enzyme hydrolyze the glycosidic bonds of the starch.
- Then the food is mixed with gastric juice in stomach, which contains mucus, hydrochloric acid, pepsin, renin and a weak lipase enzyme. The pepsin hydrolyzes proteins into proteose and peptones.
So, if the pepsin is absent then the event of breaking proteins into peptides will be affected in stomach and the correct option is b.
