A
Protein
B
Lipids
C
Carbohydrate
D
Nucleic Acid
Explanation: 

Detailed explanation-1: -The function of the biomolecule protein is structure or support and enzymes speed up the chemical reactions.

Detailed explanation-2: -A fundamental task of proteins is to act as enzymes-catalysts that increase the rate of virtually all the chemical reactions within cells.

Detailed explanation-3: -Explanation: Enzymes are biological proteins. They are catalysts and help speed up chemical reactions within the body.

Detailed explanation-4: -Answer and Explanation: The class of biomolecules in which enzymes belong are proteins.

Detailed explanation-5: -The answer is enzymes. Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits.
