Final answer:
Enzymes are proteins, triglycerides and steroids are lipids, polypeptides are chains of amino acids, DNA is a nucleic acid, and sucrose is a carbohydrate.
Step-by-step explanation:
A. Enzymes - Enzymes are a type of protein, which is one of the four major classes of organic compounds. They are responsible for catalyzing chemical reactions in the body.
C. Triglycerides - Triglycerides are a type of lipid, which is another major class of organic compounds. They function as energy storage molecules in the body and are made up of fatty acids and glycerol.
E. Steroids - Steroids are also a type of lipid. They have a unique structure with four fused carbon rings and are involved in various physiological processes in the body.
G. Polypeptides - Polypeptides are chains of amino acids and are a primary component of proteins. They play a crucial role in various biological processes.
H. DNA - DNA is a type of nucleic acid, which is the fourth major class of organic compounds. It carries genetic information and serves as a blueprint for the synthesis of proteins.
I. Sucrose - Sucrose is a type of carbohydrate and is composed of glucose and fructose. It is commonly known as table sugar.
