1 answer:

3 0

It’s between b and d. I would go with b based on the information below.

The four primary functions of carbohydrates in the body are to provide energy, store energy, build macromolecules, and spare protein and fat for other uses. Simple carbohydrates are quick energy sources, but they do not usually supply any other nutrients or fiber. One of the most important functions of carbohydrates is to form a structure called the glycocalyx. This is a coat around the cell.

tangare [24]

<h3><u>Answer</u>;</h3>

d. Na+

<h3><u>Explanation</u>;</h3>

The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others.
<em><u>Small molecules that are non-polar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.</u></em>
Charged ions such as N+ and K+ Cannot permeate the cell membrane for the since uncharged molecules repel uncharged molecules present in the membrane structure.
