Answer:

The correct answer is option d. "an enzyme"

Explanation:

Enzymes are naturally occurring catalysts that speed up a chemical reaction by lowering the activation energy needed for the reaction to take place. Enzymes are complex proteins in nature and are reusable since they are not denatured or destroyed as a result of the reaction. Enzymes are among the most important proteins in nature, since they regulate metabolism as well as the reactions needed for DNA replication and protein translation.

The synthesis of amino acids occurs in about 5 or 6 related families of amino acids. True or false?.
Andrei [34K]

This statement is true.

<h3>How many amino acids are synthesized?</h3>

For example, humans can only synthesize 11 of the 20 standard amino acids (a.k.a. non-essential amino acid), and in time of accelerated growth, histidine can be considered an essential amino acid.

<h3>Where does amino acid synthesis occur?</h3>

The process of making proteins is called translation and involves the step-by-step addition of amino acids to a growing protein chain by a ribozyme that is called a ribosome.

<h3>Is the amino group the 5 end?</h3>

The 5-prime (5') end of the polypeptide chain that has a nitrogen atom or a 'free amino group. '

Peptide bonds connect all of the amino acids of the chain together. (Norman, 7/22/09) When two or more amino acids are linked together, one end of the resulting molecule has a free amino group.
