Question

refer to the passage and diagram. what functional groups will be joined together if alanine and serine molecules combine to form a single molecule? amino acids are named after two of their functional groups: the amino group (nh2), which acts like a base, and the carboxyl group (cooh), which acts like an acid. a third functional group, often called the r group, varies among the different types of amino acids. in alanine, the r group is a methyl group (ch3). in serine, the r group is a methyl alcohol (-ch2oh). choose an amino group and a carboxyl group two amino groups an amino group and a methyl group a hydrogen atom and a methyl group hydrase change the reaction

Explanation:

Amino acids combine via a peptide - bond formed between the amino group of one amino acid and the carboxyl group of another through a dehydration - synthesis reaction.

Answer:

an amino group and a carboxyl group
