Question

what would most likely happen to a person who is not getting enough essential amino acids in his or her diet?
the body would synthesize the amino acids.
muscle growth and repair would be limited.
stored protein would break down.
the formation of proteins would increase.

Explanation:

Essential amino acids cannot be synthesized by the body and must be obtained from the diet. Proteins are made up of amino acids. Muscles are mainly composed of proteins. If there are not enough essential amino acids, there won't be sufficient building blocks for protein synthesis, which is crucial for muscle growth and repair.
The body cannot synthesize essential amino acids (so the first option is wrong). Stored protein breaking down is not the most direct and likely consequence compared to muscle - related issues. The formation of proteins would decrease, not increase (so the fourth option is wrong).

Answer:

Muscle growth and repair would be limited.
