The energy of activation of a reaction is:
A)the net change in free energy.
B)the difference in energy between substrate and product.
C)the energy input needed to reach the transition state.
D)the difference in energy between the transition state and the product.
E)equivalent to the $\Delta$G of ATP hydrolysis.

Question

Quizplus · Accepted Answer

The energy of activation is the amount of energy required to reach the transition state, which is the point in the reaction where the old bonds are breaking and new ones are forming. It is not the net change in free energy (A), the difference in energy between substrate and product (B), or the difference in energy between the transition state and the product (D). The last option (E) is not relevant to the question.

The Energy of Activation of a Reaction Is: A)the Net Δ\DeltaΔ

The Energy of Activation of a Reaction Is:
A)the Net $\Delta$
