Question

match each function, or job, with the macromolecule that fills that role in a cell. each macromolecule answer choice will be used more than once. 1. main source of energy. 2. makes up plant cell walls. 3. transports chemicals into and out of cells. 4. stores information for building proteins. 5. speeds up chemical reactions. 6. stores energy for later use. 7. protects against heat loss. protein carbohydrate nucleic acid protein lipid protein nucleic acid carbohydrate

Explanation:

Proteins can speed - up chemical reactions (as enzymes), transport chemicals, and make up plant cell walls. Nucleic acids store information for building proteins and pass information about traits to offspring. Carbohydrates are the main source of energy and can insulate against heat loss. Lipids also play roles in energy storage and are part of cell membranes but don't match all the given functions as well as the others for their respective descriptions.

Answer:

• Speeds up chemical reactions: Protein
• Stores information for building proteins: Nucleic Acid
• Transports chemicals into and out of cells: Protein
• Makes up plant cell walls: Protein
• Main source of energy: Carbohydrate
• Insulates against heat loss: Carbohydrate
• Passes information about traits to offspring: Nucleic Acid
