Graph 1 shows a reaction without an enzyme because the activation energy is lower than in Graph 2.
Graph 1 shows a reaction with an enzyme because the activation energy is higher than in Graph 2.
O c
Graph 2 shows a reaction without an enzyme because the activation energy is higher than in Graph 1.
OD Graph 2 shows a reaction with an enzyme because the activation energy is lower than in Graph 1.
