Question

which of the following best describes the primary function of carbohydrates in living organisms?
catalysis of biological reactions.
storage of genetic information.
formation of cell membranes.
short - term energy storage and structural support.

lipids are a diverse group of macromolecules with various functions. which of the following is a primary role of lipids in animals?
acting as enzymes to speed up reactions.
transmitting hereditary information.
providing the main structural component of cell walls.
long - term energy storage and insulation.

enzymes are biological catalysts that speed up chemical reactions. these molecules are classified as which type of biological macromolecule?
lipids
carbohydrates
proteins
nucleic acids

nucleic acids, such as dna and rna, carry genetic information. what are the monomers that make up nucleic acids?
fatty acids
nucleotides
amino acids
monosaccharides

Explanation:

1. Carbohydrates are mainly for short - term energy storage and can also provide structural support in some organisms. Enzymes catalyze reactions, nucleic acids store genetic information, and lipids are involved in cell - membrane formation.
2. Lipids in animals serve as long - term energy storage and provide insulation. Enzymes are proteins, nucleic acids transmit hereditary information, and cell walls in plants (not animals) have a different main structural component.
3. Enzymes are proteins. Lipids are for energy storage and membrane formation, carbohydrates are for energy and structure, and nucleic acids carry genetic information.
4. Nucleic acids are made up of nucleotides. Fatty acids are part of lipids, amino acids are the building blocks of proteins, and monosaccharides are the monomers of carbohydrates.

Answer:

1. Short - term energy storage and structural support.
2. Long - term energy storage and insulation.
3. Proteins
4. Nucleotides
