Which sequence correctly represents enzyme catalysis?
- A. E + P → EP → ES → E + S
- B. ES → E + S → E + P
- C. E + S → ES → EP → E + P
- D. EP → ES → E + S
Explanation
Enzyme and substrate first form the enzyme-substrate complex, which converts to an enzyme-product complex before releasing product and regenerating the free enzyme. Any sequence that starts from product runs the pathway backwards.
