Question

match the macromolecule to the appropriate functions. stores and decodes hereditary information, and used in energy production primary energy source in cells, energy storage in plants, and structural component of cell walls used for transport, movement, structural support, and to speed up chemical reactions primary energy storage in animals, main component of cell and organelle membranes, and used for insulation 1. carbohydrate 2. protein 3. lipid 4. nucleic acid question 6 (6 points) identify each example as either a monosaccharide, disacchride or polysaccharide.

Explanation:

• Nucleic acid: DNA and RNA (nucleic acids) store and decode hereditary information. Some nucleotides (components of nucleic acids) can also be involved in energy - related processes (e.g., ATP).
• Carbohydrate: Glucose (a monosaccharide, a type of carbohydrate) is the primary energy source in cells. Starch (a polysaccharide) is an energy storage in plants, and cellulose (a polysaccharide) is a structural component of plant cell walls.
• Protein: Proteins have diverse functions. Transport proteins (e.g., hemoglobin transports oxygen), motor proteins (e.g., myosin for muscle movement), structural proteins (e.g., collagen for structural support), and enzymes (a type of protein) speed up chemical reactions.
• Lipid: Triglycerides (a type of lipid) are the primary energy storage in animals. Phospholipids are the main component of cell and organelle membranes. Lipids like fats can also be used for insulation.

Answer:

• “stores and decodes hereditary information, and used in energy production” → 4. nucleic acid
• “primary energy source in cells, energy storage in plants, and structural component of cell walls” → 1. carbohydrate
• “used for transport, movement, structural support, and to speed up chemical reactions” → 2. protein
• “primary energy storage in animals, main component of cell and organelle membranes, and used for insulation” → 3. lipid
