What are enzymes
1. chemical compounds that protect the body
2. proteins that affect the rate of chemical changes in organic substances
3. organic compounds that break down into energy
4. parts of cells that them to divide

Enzymes are molecules, mainly proteins that affect the chemical reaction in cells.

Explanation:

The biological molecules, basically proteins that regulate all the chemical reactions in organic substances are called enzymes. Enzymes widely help in body functioning, such as- digestion and increasing metabolism. They can both break and combine molecules.

Enzymes make the chemical reactions speedy. A particular reaction is regulated by a single enzyme. Enzyme deficiency can lead to many diseases.  The enzymes work with molecules like substrates.
