Check all steps in a reaction catalyzed by an enzyme:
Substrate binds to enzyme
Enzyme is changed as it moves on to the next reaction
Products are released from the enzyme
Enzyme fits to the substrate in an induced fit
An enzyme catalyzes a reaction meaning...
it speeds up the reaction by raising the activation energy
it speeds up the reaction by lowering the activation energy
it slows down the reaction by raising the activation energy
it slows down the reaction by lowering the activation energy
