Multiple choice

Which of the following statements regrading enzyme catalysis is INCORRECT?

  1. The mechanism of enzyme catalysis is similar in principle to other types of chemical catalysis.

  2. Enzymes provide an alternative reaction route.

  3. The induced fit model proposes that the initial interaction between the enzyme and the substrate is very strong.

  4. The advantages of the induced fit mechanism arise due to the stabilising effect of strong enzyme binding.

  5. Saturated enzymes have a high affinity substrate binding capacity.

C Correct answer
Explanation

The favoured model for the enzyme-substrate interaction is the induced fit model. This model proposes that the initial interaction between the enzyme and the substrate is relatively weak.
