Based on your text, answer the following questions.
Now that John is eating protein bars and shakes, he is consuming more protein and calories daily than he requires. What most likely happens to the excess protein?
A) It is converted to muscle tissue.
B) It is stored until needed for muscle tissue repair.
C) It is converted to fat for energy storage.
D) It is converted to glucose for energy.
E) It is used to synthesize essential amino acids.

When the body has an excess of protein, it goes through a process called deamination, where the nitrogen from the amino acids is removed and the carbon chains are converted to glucose or fatty acids, which can then be stored as fat. This process requires energy, so consuming excess protein will not automatically lead to muscle growth.
