Answer 1

Answer:

d

Explanation:

All of these is correct

Hence, D) Option

Thanks!

Answer 2

The correct answer is All of these (option d) as the enzyme pepsin and trypsin differs in all the aspects mentioned here.

• Substance they break down

Pepsin is an enzyme that breaks down protein molecules into smaller peptides in the stomach, where the pH is extremely acidic.

Inside the small intestine, trypsin is an enzyme that transforms partially digested proteins into dipeptides and amino acids at an alkaline pH.

• Optimum pH

The ideal pH for pepsin is 1.5, with a pH range of 1.5 to 3.5.

The ideal pH range for trypsin is between 7 and 9, with optimal action at pH 8.

• Site of secretion

Pepsin is released by gastric main cells in the stomach as inactive pepsinogen, which is then converted to an active form. It depicts the activity within the stomach.

Trypsin is secreted by pancreatic cells as inactive trypsinogen, which is eventually converted to its active form. To demonstrate its digestive role, it is secreted into the small intestine.
