Question

Binding energy released in enzyme-substrate complex formation causes the
A) decrease in the free energy of product
B) decrease in the free energy of substrate
C) increase in the activation energy
D) decrease in the activation energy

ANSWER IFF YOU'RE SURE...

Answer 1

I thought opttionA is correct.

Answer 2

Answer:

Option D) Decrease in the activation energy

Explanation:

• The transition state is an unstable, activated complex that develops at some point in the reaction between the substrate (S) and the products (P), and has the highest free energy in a reaction pathway.

• At this transition state, the enzyme attaches to the substrate to form an Enzyme-substrate complex by forming a weak chemical bond.

• And the binding energy or the separation energy is that free energy released by the formation of such weak interactions. Such an interaction between the enzyme and the transition state gives a path to the maximum binding state.
• Upon which the activation energy gets lowered or reduced that will speed up or accelerate the reaction to proceed fast.

Hence the binding energy released in enzyme-substrate [ES] complex formation causes the option D) decrease in the activation energy is correct.
