After a polypeptide chain has been synthesized, certain amino acids in the peptide may become modified. For each modified amino acid, identify the standard amino acid from which it is derived. Enter the abbreviated name of the standard amino acid.

standard amino acids is an amino acid used in the synthesis of peptides

Explanation: There are twenty standard amino acids which are

ALA, ARG, ASN, ASP, CYS, GLN,GLU,GLY,

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

1. what is the relationship between the shape of an enzyme and the reactions they catalyze?

2. how does an enzyme inhibitor work?

separate your answers so i dont get confused : )
