Which of the following statements regarding the catalytic cycle of enzyme action is/are correct?
i. The substrate binds to the active site of the enzyme, fitting perfectly into it.
ii. The enzyme changes shape to fit more tightly around the substrate after binding occurs.
iii. The enzyme-product complex is formed when the active site breaks the chemical bonds of the substrate.
iv. The enzyme remains permanently altered after releasing the products of the reaction.
  • a)
    ii and iii

    i and ii
  • c)
    iii and iv
  • d)
    i, ii, and iii

Which of the following statements regarding the catalytic cycle of enz...
To determine which statements are correct, let's analyze each one:
- Statement i: This statement describes the initial binding of the substrate to the enzyme's active site, which is accurate as enzymes typically have specific active sites that fit their substrates (the "lock and key" model).
- Statement ii: This statement is also correct. After the substrate binds, the enzyme undergoes an "induced fit," altering its shape for a tighter fit around the substrate.
- Statement iii: This statement correctly describes the formation of the enzyme-product complex, where the active site facilitates the breaking of chemical bonds in the substrate.
- Statement iv: This statement is incorrect. Enzymes are not permanently altered after the reaction; they can be reused to catalyze additional reactions.
Thus, the correct statements are i, ii, and iii, leading to the correct answer being Option D.
