The active site of an enzyme______________?
Correct answer: C. Determined by structure and the specificity of the enzyme
- A. Never changes
- B. Forms no chemical bond with substrate
- C. Determined by structure and the specificity of the enzyme
- D. They are non specific in their action
Explanation
The active site's shape and chemical groups arise from the enzyme's three-dimensional structure, giving the enzyme specificity for particular substrates. A common mistake is choosing a because the active site may adjust slightly during induced fit, but it is not completely unchanging in every enzyme.
