Which of the following BEST describes the biological function of a macromolecule?

The group of choices is as follows:

Proteins' primary function is to provide energy to cells.

Lipids' unique 3D structure determines their function.

Nucleic acids are critical components of plant cell walls.

Carbohydrates include glucose, a critical molecule for cellular respiration

The correct answer is - Carbohydrates include glucose, a critical molecule for cellular respiration

Explanation:

Macromolecules are the large molecules of nutrients that are made by the polymerization of monomers or smaller subunits and perform various cellular functions. These molecules are protein, carbohydrate and nucleic acids.

The biological function of these molecules is not limited but they have different primary functions and among the given group of choices the best function is carbohydrate perform cellular respiration to produce energy as its primary function to provide energy to cells.

c.more precipitation,but only when emission levels.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
