activation energy EA
Enzymes lower the activation energy (EA) of reactions.
induced-fit model -
Enzymes reduce EA by:
Why do enzymes operate at an optimal temperature and pH?
competitive inhibitor –
noncompetitive inhibitor –
allosteric site –
allosteric activator –
allosteric inhibitor –
A, B, C and D are molecules along a metabolic pathway.
E1, E2 and E3 are enzymes required for this metabolic pathway.
D is an allosteric inhibitor of E1.
