What is the next step in the process after a substrate enters the active site of an enzyme?

a) the chemical reaction occurs.
b) new substances called products are formed.
c) the enzyme and the substrate bind to form the enzyme-substrate complex.
d) the enzyme and the products bind to form the enzyme-products complex.

Correct C). The enzyme and the substrate bind to form the enzyme-substrate complex.

Enzymes are known as the biological catalyst that is known to increase the rate of biochemical reaction by lowering the activation energy of the reaction.

The substrate enters the active site of the specific enzyme. The specificity of the enzyme is determined by the shape complementarity and the non-covalent interactions. These interactions are known to bring some changes in the shape of the enzyme, which form the enzyme-substrate complex.

These interactions bring some changes in the shape of the active site of the enzyme which results in the formation of the enzyme-substrate complex. After that catalysis occurs which convert substrate into the product.
