alleryWhich sequence correctly represents an enzyme’s catalytic cycle?
AProduct binds → enzyme destroyed → substrate released
BEnzyme consumed → substrate binds → product released
CSubstrate released → product binds → enzyme destroyed
DSubstrate binds → conversion occurs → product released
Answer & Solution
Correct answer: D. Substrate binds → conversion occurs → product released
Substrate first binds the active site, forming an enzyme–substrate complex. Catalysis produces an enzyme–product complex, then products leave and the enzyme can act again.
