Question

molecule 1: certain sugar, phosphate and nitrogen base, example: a, uses: heredity information; molecule 2: monosaccharides, example: glucose, uses: b; molecule 3: c, example: steroid, uses: energy storage; molecule 4: contain amino and carboxyl groups, example: d, uses: reaction regulation, transport, movement. which of the following correctly completes the table? a=dna or rna, b=cell fuel and support, c=galactose and glycogen, d=nucleic acids and fatty acids; a=dna or rna, b=cell fuel and support, c=fatty acids and glycerol, d=hemoglobin and amylase

Explanation:

Molecule 1 with sugar, phosphate and nitrogen base is a nucleotide, examples are DNA or RNA used for heredity information. Molecule 2 with monosaccharides like glucose is a carbohydrate used as cell fuel and for support. Molecule 3 with steroid example is a lipid, made of fatty - acids and glycerol used for energy storage. Molecule 4 with amino and carboxyl groups is a protein, examples like hemoglobin and amylase are used for reaction regulation, transport and movement.

Answer:

A=DNA or RNA, B=cell fuel and support, C=fatty acids and glycerol, D=hemoglobin and amylase
