This macromolecule controls the rate of reactions, regulates cell processes, forms cellular structures, carry substances in and out of the cell, and helps fight disease.
A
Carbohydrates
B
Proteins
C
Lipids
D
Nucleic Acid
Explanation: 

Detailed explanation-1: -The functions of proteins are they control the rate of reaction, regulate cell processes, form important cell structures, or transport substances to help fight diseases. The functions of Nucleic Acids are they transmit and store heredity, or genetic, information.

Detailed explanation-2: -Nucleic acids are key macromolecules in the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Detailed explanation-3: -The macromolecule that functions in the selective acceleration of a chemical reaction is a protein known as an enzyme. An enzyme is a biological catalyst, a catalyst lowers the activation energy of a chemical reaction allowing it to proceed at a faster rate with a lower input of energy.

Detailed explanation-4: -The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
