Question

which statement describes the formation of a protein molecule?
a. amino acids combine to form a protein chain.
b. fatty acid monomers dissolve to form a protein chain.
c. fatty acid monomers combine to form a protein chain.
d. amino acids dissolve monomers to form a protein chain.

Explanation:

To determine the correct statement about protein formation, recall that proteins are polymers made of amino acid monomers. Amino acids undergo dehydration synthesis (combine) to form peptide bonds, creating a protein chain. Fatty acids are monomers for lipids, not proteins, so options with fatty acids (B, C) are incorrect. Option D is wrong as amino acids are the monomers, not dissolving monomers. Only A correctly states amino acids combine to form a protein chain.

Answer:

A. Amino acids combine to form a protein chain.
