Question

using the picture to the right, explain how an enzyme works.

Explanation:

Enzymes are biological catalysts. The substrate binds to the active - site of the enzyme in a lock - and - key or induced - fit manner. Once bound, the enzyme lowers the activation energy of the reaction, facilitating the conversion of the substrate into products. After the reaction, the products are released from the active - site, allowing the enzyme to bind to another substrate molecule.

Answer:

Enzymes have an active - site where the substrate binds. The binding lowers the activation energy of the reaction, converting the substrate into products which are then released, enabling the enzyme to act again.
