The cell membrane is selectively permeable because of its molecular structure. Based on this, which one of these would NOT diffuse

directly through the cell membrane?

A)

macromolecules

6)

alcohol and glycerol

small, noncharged molecules

0, and Co

Option A) macromolecules

Explanation:

The cell membrane is selectively permeable due to its molecular structure, only small molecules such as nutrients like Sodium, Potassium, glucose, oxygen and carbondioxide etc pass through them. Macromolecules such as carbohydrates, proteins and lipids are bigger in size so they cannot pass through cell membrane.
