Before amino acids are catabolized for energy yielding pathways, they must first undergo what step?

Question options:

removal of the amino groups (-NH2).

hydrolysis of the peptide bond.

removal of the carboxyl groups (-COOH).

condensation of the peptide bond.

A

Explanation:

Before the enzyme can enter the energy-yielding pathways, its amino acids must first be deaminated. In other words, the amino groups must be removed from the amino acids.

Only A matches this description, so that's the answer.

Hope this helps!

removal of the amino groups (-NH2).

Explanation:

First step is the removal of the amino group.

1. a host loses nutrients to a parasite
