Question

In which of the following respect, the plant hormones differ from enzymes?

• A. They are required in less quantity.
• B. They are expanded in the process.
• C. They release some energy.
• D. None of the above.

Answer 1

The correct option is D None of the above.

Enzymes are biological catalysts, produced at one site and action in that site. They remain the same at the end of the reaction, they are not used up.
Hormones are not catalysts, but will initiate reactions, produced at origin site and action at target site. They take part in reaction and are thus used up in the end.
