Question

What is the catalytic cycle of an enzyme?

Answer 1

An enzyme is a biological catalyst. It is a biochemical compound that helps to speed up reactions that occur in the body and make them more efficient. Enzymes are integral to the way our body functions.

Complete answer:
The enzyme is a molecule that is a catalyst in the body. Another molecule, known as the substrate has to bind to the enzyme in order to set off the reaction. Thus this process is known as a catalytic cycle. There are four steps that occur in this cycle:
1. First, the substrate binds to the enzyme molecule. It binds to a specific region known as the active site of the enzyme.
2. Once this happens, an enzyme-substrate complex is formed. When the substrate binds to the enzyme, it changes the shape of the enzyme so that no other molecules can bind to it.
3. Next, the enzyme breaks certain chemical bonds within the substrate and changes it. This forms the enzyme-product complex.
4. Eventually, after this enzyme-product complex is formed, the enzyme is released from the product so the product can be used by the body. Thus the enzyme is then free for other substrates to bind to it.

Note:
The catalytic cycle of an enzyme is the process that an enzyme undergoes to produce a product. The substrate has to bind to the enzyme in order to begin this entire process. It has four different parts.
