Rachel and Mark are discussing the requirements of a healthy diet. Rachel says that essential amino acids come from a mix of complete and incomplete proteins. Mark says only complete proteins can provide amino acids to the body. Who is correct?

Question

Question 18 options:

A)

Mark is correct.

B)

Both Rachel and Mark are correct.

C)

Neither Rachel nor Mark is correct.

D)

Rachel is correct.

Answer 1

D) Rachel is correct.

Rachel is correct because the body can obtain essential amino acids from both complete proteins (which contain all nine essential amino acids) and a combination of incomplete proteins (which do not contain all essential amino acids but can be paired together to provide the necessary amino acids). Mark is incorrect in stating that only complete proteins can provide amino acids to the body.
