How do enzymes speed up reactions?
A.They lower the activation energy
B.They raise the temperature of the cell
C.They add energy to the products
D.They change the equilibrium constant
Explanation
Core Concept
Enzymes stabilize the transition state so less energy is needed to reach it, letting more collisions succeed. ΔG of the reaction is unchanged.
Correct Answer
AThey lower the activation energy
