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.
Helium does not react with any other substances, thus the substance’s internal structure is never greatly affected and thus helium cannot have any chemical properties.
