Final answer:
When an essential amino acid is missing from the diet, it can lead to protein deficiency and various health problems. Essential amino acids cannot be synthesized by the body and must be obtained from food. If a person lacks one or more essential amino acids in their diet, their body will not be able to produce proteins that play essential roles in growth, repair, and maintenance of tissues.
Step-by-step explanation:
When an essential amino acid is missing from the diet, it can lead to protein deficiency and various health problems. Essential amino acids cannot be synthesized by the body and must be obtained from food. If a person lacks one or more essential amino acids in their diet, their body will not be able to produce proteins that play essential roles in growth, repair, and maintenance of tissues. For example, the lack of the essential amino acid lysine, which is deficient in wheat, rice, and oats, can result in impaired growth and development.
