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.

Answer 1

Muscle growth and repair would be limited.

Essential amino acids cannot be made by the body, so without enough in the diet protein synthesis is impaired. That both limits new muscle growth/repair and forces the body to break down stored protein (muscle) to supply needed amino acids.
