How do small molecules get through a cell membrane
A vesicle forms as a small sac from the cell's membrane.
the cell lining of the small intestine is called villi and are small, finger-like projections that are used to increase surface area.
the cell membrane
Because it is a small molecule, water can diffuse through the cell membrane.
Small particles move faster across the membrane.
