Question

Part of active site of enzyme, where substrate is supported is

• A. Catalytic group
• B. Buttressing group
• C. Activation chamber
• D. K constant

Answer 1

The correct option is B Buttressing group

A catalytic group is the part of the active site of the enzyme that promotes enzyme-substrate interaction and thereby formation of transition state by promoting breaking old bonds and formation of new bonds. The buttressing group is the part of the active site of enzymes that supports substrate by providing the substrate binding site. The active sites have only two parts; catalytic group and buttressing group. Thus, the correct answer is option B.
