a. Is where the semi-permeable membrane is located
b. Is a specific bulge of protuberance on an enzyme
C. Is a groove or crevice in the structure of the enzyme into which the substrate fits
d. Rigidly resists any alteration of its shape
<h3><u>Answer</u><u>:</u><u>-</u></h3>
C. Is a groove or crevice in the structure of the enzyme into which the substrate fits.
<h3><u>Explanation</u><u>:</u><u>-</u></h3>
The active site is one such gap or pocket to which the substrate adapts and binds to the enzyme.
The active site is the region of the enzyme to which the substrate molecule binds and causes a chemical reaction. The active site is composed of amino acid residues that form a temporary bond with the substrate.
