BIOCHEMISTRY

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The substance on which an enzyme acts is the:
A
product
B
substrate
C
active site
D
activation energy
Explanation: 

Detailed explanation-1: -The substance which reacts with the enzyme to form the product is called substrate. The part of the enzyme where the substrate binds is called the active site. The enzyme reacts with the substrate to form enzyme-substrate complex followed by formation of the product.

Detailed explanation-2: -Biochemistry. In biochemistry, the substrate is a molecule upon which an enzyme acts. Enzymes catalyze chemical reactions involving the substrate(s). In the case of a single substrate, the substrate bonds with the enzyme active site, and an enzyme-substrate complex is formed.

Detailed explanation-3: -Substrates are the substances that an enzyme acts on. They tend to be the original reactant, and the newly formed material is the product(s). Enzymes can be proteins or RNA molecules (ribozymes). The enzyme is not used up during the process, so it can repeat the reaction as needed for biologic functions.
