Answer: This is a positive feedback loop.
Explanation:
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.

Neutralization Reaction:
- When an acid and an alkali react chemically, they form water and a corresponding salt. This reaction called the neutralization reaction.
- acid + base (alkali) → salt + water
- E.g HCl + NaOH → NaCl + H2O
- The formic acid that the ant injects can be neutralization by application of an alkali.
- In order to prevent a serious allergic reaction, antihistamines must also be administered.
