Question

question 3 (multiple choice worth 3 points) (01 03 mc) a carbohydrate molecule is a macromolecule made of amino acids that provides structure for a cell and is not soluble in water made up of a chain of monosaccharides that transport genetic coding from one end of the cell to another made up of the monosaccharide glucose and serves as an energy reserve in plants and animals a chain of amino acids that can be used for protein synthesis, protection, and increasing reaction speeds

Explanation:

Carbohydrates are made up of monosaccharides. Glucose is a monosaccharide. Starch (in plants) and glycogen (in animals) are polysaccharides (chains of monosaccharides) that serve as energy - reserves.

• Option 1: A macromolecule made of amino acids is a protein, not a carbohydrate. Proteins can provide structure (e.g., collagen) and some proteins are insoluble in water.
• Option 2: Nucleic acids (DNA and RNA) transport genetic coding, not carbohydrates.
• Option 4: A chain of amino acids is a protein. Proteins are used for protein synthesis (as enzymes can help in the process), protection (e.g., antibodies), and increasing reaction speeds (enzymes are proteins that act as catalysts).

Answer:

C. made up of the monosaccharide glucose and serves as an energy reserve in plants and animals
