Question

match each function with the correct macromolecule
carries genetic information for the cell
provides short - term energy for cells and structure in plant cells
help catalyze chemical reactions in cells
provides long - term energy, protection/insulation, and helps with cell membrane structure

Explanation:

1. DNA (a nucleic - acid) carries genetic information for the cell. Nucleic acids are composed of nucleotides and store and transmit genetic information.
2. Carbohydrates provide short - term energy for cells and structure in plant cells. Monosaccharides are the building blocks of carbohydrates and are quickly metabolized for energy, and cellulose (a polysaccharide) provides structure in plant cell walls.
3. Enzymes, which are proteins, help catalyze chemical reactions in cells. Enzymes lower the activation energy of reactions, increasing the reaction rate.
4. Lipids provide long - term energy, protection/insulation, and help with cell membrane structure. Fats are used for long - term energy storage, waxes can provide protection, and phospholipids are a major component of cell membranes.

Answer:

1. Carries genetic information for the cell: Nucleic acid
2. Provides short - term energy for cells and structure in plant cells: Carbohydrate
3. Help catalyze chemical reactions in cells: Protein
4. Provides long - term energy, protection/insulation, and helps with cell membrane structure: Lipid
