According to the induced fit model, what happens when an enzyme-substrate complex is formed?
Correct answer: A. The contact between the substrate and the enzyme causes a change in the shape of the active site.
- A. The contact between the substrate and the enzyme causes a change in the shape of the active site.
- B. The shape of the substrate and the shape of the active site are complementary to each other
- C. The substrate fits into the active site and forms bonds with the amino acids at the active site
- D. All of the above
Explanation
The enzyme substrate complex is a temporary molecule formed when an enzyme comes into perfect contact with its substrate.The substrate causes a conformational change, or shape change, when the substrate enters the active site. The active site is the area of the enzyme capable of forming weak bonds with the substrate. Therefore, option A is correct.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
