Question

Regarding catalytic cycle of an enzyme action, select the correct sequential steps :
A. Substrate enzyme complex formation. 
B. Free enzyme ready to bind with another substrate. 
C. Release of products. 
D. Chemical bonds of the substrate broken. 
E. Substrate binding to active site. 
Choose the correct answer from the options given below :

• A. E, A, D, C, B
• B. A, E, B, D, C
• C. B, A, C, D, E
• D. E, D, C, B, A

Answer 1

The Correct Option is A

Sequence of Enzyme Action:

• E. Substrate binding to the active site occurs first.
• A. Substrate-enzyme complex formation follows after the substrate binds to the active site.
• D. Chemical bonds of the substrate are broken, leading to the formation of products.
• C. Release of products occurs next.
• B. Free enzyme is ready to bind with another substrate to complete the cycle.

Thus, the correct answer is (1) E, A, D, C, B.
