This is what makes the body function: enzymes are the protein molecules that catalyze the biochemical reactions the body carries on. The enzyme activities of metabolism include the breaking down of nutrients into synthesizing even more complex molecules, so such life supporting processes become routine daily activities. Some examples of enzymes present in the body include digestive enzymes that may break down food and metabolic that helps us to produce energy.

The mechanism of enzyme catalysis is based on the particular interaction between an enzyme and its substrates, namely the fact that a substrate binds to an active site for the purpose of reducing the activation energy required for reactions. The shape is important to the function and specificity of an enzyme since an enzyme itself is in a protein structure.

Enzyme kinetics and regulation control the rate of reactions that are environmental (temperature, pH)&cellular-themed concentrates. They are used in food processing, biotechnology, and others including industrial. Enzyme inhibitors and activators may well be able to control the activity of enzymes making them a key also in medicine and research.
