Is the following an example of a. Negative feedback loop b. Positive feedback loop Hydrochloric acid and pepsin are enzymes secreted by cells in your stomach to digest proteins. The presence of partially digested protein in the stomach triggers the secretion of more hydrochloric acid and pepsin. Thus, once digestion begins, it becomes a self-accelerating process. Is the following an example of a. Negative feedback loop b. Positive feedback loop

The protein digestion in the body is an example of the positive feedback. The gastric secretions is stimulated chiefly by the action of three chemicals.

These chemicals are acetylcholine, histamin and gastrin. These chemicals stimulate the parietal cells to secrete HCL and intrinsic factors.

The chief cells secrete pepsinogen in response to the gastrin and ACh. As the dietary proteins are digested, it breaks down the amino acids and peptides.

This stimulates the G cells of the stomach to secrete more gastrin. This is how the positive feedback loop for the protein digestion works.

It is an illustration of a positive feedback loop.

• The digestion of protein within the body is an illustration of the positive feedback.

• The secretions of gastric juice is instigated mainly the activity of three chemicals, these are histamine, acetylcholine, and gastrin.

• With the assistance of these chemicals, the parietal cells get instigate to discharge hydrochloric acid and intrinsic factors.

• In response to the gastrin and acetylcholine, the chief cells discharge pepsinogen, with the digestion of proteins, it get dissociate to peptides and amino acids.

• This further instigates the G cells of the stomach to discharge more gastrin. This is the manner in which positive feedback loop works during the digestion of protein.

Thus, it is the positive feedback loop.
