Question

What is true if enzymes

Answer 1

I may be wrong but I think it’s the second one. They speed up reactions, and there’s a certain enzyme for a certain reaction.

Answer 2

Answer:

Option (2).

Explanation:

Enzymes are made of proteins that have the specific amino acid sequences. Enzymes have well determined 3D shape and work in their specific shape and at specific physical and chemical condition.

Enzymes may acts as catalyst that can increase the rate of the bio chemical reaction. Each enzyme is specific for one reaction and lowers the activation energy of the reaction. Enzymes increases the effective collision between the substrate molecule and increases reaction rate.

Thus, the correct answer is option (2).
