How do enzymes reactions in the cell?

Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells.

They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.

Enzymes are biological catalysts. Catalysts lower the activation energy forreactions. The lower the activation energy for a reaction, the faster the rate. Thusenzymes speed up reactions by lowering activation energy.
