are the following;
<span>·
</span>Plasma free fatty acids – this is used as an
energy in which they provide in every organs in the body of a living organism.
<span>·
</span>Blood glucose – The glucose can provide energy
in the body in which they are found in the sugar of the blood.
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
Answer:
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.
