Default Trypsin and elastase are both enzymes that catalyze hydrolysis of peptide bonds.?



But trypsin only cuts next to lysine and elastase only cuts next to alanine. Why?
A. Trypsin is a protein, and elastase is not
B. two reactions are different
C. The shape of the active site for the two are different
D. One of the reactions is endergonic and the other exergonic
E. hydrolysis of lysine bonds require water, hydrolysis of alanine bonds does not

C. The shape of the active site for the two are different

This is usually the difference between similar enzymes. This is basically what lends specificity or selectivity to the enzyme.
