Answer:
Certain proteins
Step-by-step explanation:
Amino acids are essential for human life. We could say that they are the "bricks" with which proteins are built.
Although our body is made up of about 250,000 different proteins, they are made up of only 20 amino acids - and our body is capable of making only 11 of them. The other nine - histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine - are called essential amino acids. As they cannot be synthesized by the human body, we must achieve them through food.
Accordingly, we can say that if Tyler does not eat a diet that includes essential amino acids, his cells will not be able to make certain proteins.
