1
Q
Activation Energy
A
Input of energy required to start a chemical reaction
2
Q
Active Site
A
Region on an enzyme molecule where the substrate binds
3
Q
Competitive inhibition
A
The slowing down of reaction rate due to the presence of a substance resembling the substrate
4
Q
Feedback inhibition
A
Enzyme inhibition caused by the presence of an end product of a metabolic pathway acting as an inhibitor of the pathway
5
Q
Induced fit
A
Change to an enzyme’s active site brought about by its substrate
6
Q
Non-competitive inhibition
A
Enzyme inhibition by a substance that permanently alters the active site of an enzyme
7
Q
Product
A
Substance resulting from an enzyme-catalysed reaction
8
Q
Substrate
A
Substance on which an enzyme acts
