Answer 2

Explanation:

The substrates for these reactions are obtained from the body's diet or from the culture medium. Not all organisms are able to synthesize all amino acids. Humans, for example, are only able to synthesize 11 of the 20 amino acids that can be found in their body, forming part of their proteins or as metabolic intermediates. The other nine are called essential amino acids and must be incorporated into the diet, the same goes for histidine during periods of rapid growth.
