Answer:

The inactive precursor to the enzyme pepsin that digests proteins in the stomach. (Ans A)

Explanation:

Pepsin is known as a digestive enzyme which is present in humans and other species digestive system. It is produced by the stomach, where it helps to digest the proteins and break down into amino acids which are present in food. In the stomach, a cell is known as a peptic or chief cell that helps to release Pepsinogen.

The Pepsinogen secreted by Chief cells is an inactive form of pepsin, on exposure to HCL (hydrochloric acid secretion from Parietal cells), gets converted to the active enzyme pepsin because HCL provides necessary acidic environments where pepsin work best. Then Pepsin hydrolyzed the proteins to polypeptide and starts protein digestion in the stomach.

marysya [2.9K]

Answer:

It can be concluded that CFS has no effect on the light production of V.harveyi.

Explanation:

The both tube contain same cell concentration of V.harveyi.Now CFS is added from a light producing V.fischeri which ultimate result in the production of light by V.harveyi.

      On the other hand V.harveyi cells present on another tube can itself produce light because according to the question fresh media is added in this tube inplace of CFS.

V.harveyi of both tubes produces same amount of light.From this point of view it can be stated that V.harveyi itself can generate light, it does not need addition of any CFS from outside.
