Which of the following statements is INCORRECT about the enzyme-substrate complex?
Options
- AIt allows the enzyme to bind more tightly to the substrate.
- BIt helps break the chemical bonds within the substrate.
- CFormation of the Enzyme-Product complex.
- DIt transforms the product back into the substrate.
Correct answer
D. It transforms the product back into the substrate.
Step-by-step solution
The catalytic cycle of an enzyme involves the binding of a substrate to the active site of the enzyme to form a transient enzyme-substrate complex. The binding of the substrate induces a conformational change in the enzyme, causing it to fit more tightly around the substrate. This makes the first statement correct. The active site of the enzyme, when in close proximity to the substrate within the complex, facilitates the breaking of chemical bonds in the substrate. This makes the second statement correct. The enzym
