Question

Template/lock and key theory of enzyme action is supported by

• A. Enzymes speed up reaction
• B. Enzymes occur in living beings and speed up certain reactions
• C. Compounds similar to substrate inhibit enzyme activity
• D. Enzymes determine the direction of reaction

Answer 1

The correct option is C

Compounds similar to substrate inhibit enzyme activity

Enzymes form a 3-D conformation where the substrate binds and enzyme activity occurs.

This imparts specificity to enzymes.

If a compound has a structure similar to the substrate, then it can bind to the enzyme and inhibit enzyme activity.
