A total of <u>20</u> amino acids compose the majority of protein in living things and nine are <u>essential</u> to human.
- All living organisms, from bacteria to people, depend on amino acids for survival.
- The same 20 types of amino acids are present in all living things.
- Only 21 amino acids are required by the human body to create all the proteins required for growth and function.
- Your body can create thousands of different types of proteins with only the same 21 amino acids because they can be ordered in a wide variety of ways.
- The body is unable to produce essential amino acids. They must therefore originate from food.
- Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine essential amino acids.

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.
