Question

What are the main characteristics of an enzyme ?

Answer 1

Main characteristics of an enzyme:

1. It is a protein and therefore, gets destroyed by heating.
2. It acts only on one kind of substance called the substrate. So, it is very specific.
3. It acts as a catalyst, so it can be used again and again.
4. It only affects the rate of a chemical reaction.
5. It always forms the same end products from the fixed substrate.
6. It acts best only at a particular pH.
7. It acts best within a narrow temperature range, usually between 35°C-40°C
