Question

What is a limiting amino acid?

a) An amino acid found in abundance in the diet
b) An amino acid that is essential for protein synthesis
c) An amino acid that restricts protein synthesis when in short supply
d) An amino acid that has no role in protein synthesis

Answer 1

A limiting amino acid restricts protein synthesis when in short supply.

Step-by-step explanation:

A limiting amino acid is c) An amino acid that restricts protein synthesis when in short supply. The body cannot synthesize certain amino acids, known as essential amino acids, and they must be obtained from the diet. When the supply of a particular essential amino acid is insufficient, it becomes the limiting amino acid and hinders protein synthesis.
