Question

Energy released from enzyme-substrate interaction is

• A. Activation energy
• B. Binding energy
• C. Constant energy
• D. Variable energy

Answer 1

The correct option is B Binding energy

The transition state is the state of the activated complex which is highly unstable and readily changes into the product. At the transition state, the enzyme attaches to the substrate to form an enzyme-substrate complex by forming a weak chemical bond. Binding energy is the free energy that is released by the formation of weak interactions between a complementary substrate and enzyme.

So, the correct answer is option B.
