A substance that controls the rate of a chemical reaction without being used up in the reaction.

A 3D-shaped protein that acts as a biological catalyst.

biological catalyst, typically a protein, that accelerates specific chemical reactions in living organisms by lowering activation energy without being consumed

The molecule formed by enzyme action

There is a small, unique depression on the surface of the enzyme called the active site. The shape of the active site matches the shape of the substrate it acts on. Substrate are changed into product when they bind to the active site and a biochemical rea

the sum of all chemical reactions in a living organism, enabling life by converting food into energy for functions like breathing, moving, and growing, and building necessary molecules (like proteins and lipids) from smaller ones

Photosynthesis, protein synthesis and DNA replication are all anabolic reactions. In DNA replication, the anabolic enzyme DNA polymerase joins individual nucleotides together to form DNA small>large
