Question

question 3 / 10
which is not a structural feature of an enzyme?
a. protein
b. substrate
c. active site
d. amino acid

Explanation:

Enzymes are proteins (A is a structural feature). Proteins are made of amino acids (D is a structural feature). Enzymes have an active site (C is a structural feature) where the substrate binds. But the substrate (B) is not a structural part of the enzyme; it is a separate molecule that the enzyme acts upon.

Answer:

B. substrate
