Answer:
Enzymes are biocatalysts which increases the rate of the biochemical reaction by lowering the activation energy of the reaction.
It performs the catalysis in four steps:
- The substrate enters the active site of a specific enzyme.
- It forms the enzyme-substrate complex with the help of non-covalent interactions such as complementary shape, hydrophobic interactions, hydrogen bonding et cetera.
- The process of catalysis takes place during which old bonds are broken or rearrange to convert the substrate into the product. It results in the formation of enzyme-product complex.
- The product has different properties as compared to the substrate due to which it gets released from the active site of the enzyme. The enzyme is ready to bind to a new substrate.
Thus, the correct answer would be the formation of the enzyme-substrate complex.
