Select all of the following that can be used to describe the structure of enzymes, the importance of the shape, and the relationship of enzyme shape and function.

a. Amino acids are linked by hydrogen bonds with various chemical groups attached to give enzymes their two dimensional shape.
b. Amino acids are linked by hydrogen bonds with various chemical groups attached to give enzymes their three dimensional shape.
c. Amino acids are linked by hydrogen bonds with various chemical groups attached to give enzymes their four dimensional shape.
d. Amino acids are linked by peptide bonds with hydrogen bonds between nearby amino and carboxyl groups to give enzymes their two dimensional shape.
e. Amino acids are linked by peptide bonds with interactions between the side groups of amino acids to give enzymes their three dimensional shape.
f. Amino acids are linked by peptide bonds with interactions between the side Amino acids are linked by peptide bonds with various chemical groups attached to give enzymes their four dimensional shape.
g. One or more polypeptide chains are folded and bond together in the fourth level of protein organization.
h. The shape of an enzyme determines its function The number of amino acids in an enzyme determines its function.
i. The active site binds with the substrate Enzymes are substrate specific.
j. Alteration of active sites does not alter the enzymatic reaction.
