What Would Happen If Activation Energy Barriers Didn't Exist

Question

What would happen if activation energy barriers didn't exist?
A) Substrates would not bind properly to enzymes.
B) Chemical reactions in the body would never occur.
C) Coenzymes would not work, but enzyme function would not be affected.
D) All chemical reactions in the body would proceed whether they were needed or not.

Accepted Answer

Activation energy barriers serve as a gatekeeper for chemical reactions, allowing only necessary reactions to occur. Without these barriers, all reactions would proceed regardless of whether they were necessary or not, leading to chaos in the body.
