Question

I was wondering if all of the choices were answers since multiple answers are possible on this question. I was really unsure on the transport of Vitamin D and cholesterol.

The normal cell membrane: Should contain proteins if the cell is going to be capable of facilitated diffusion Should contain proteins if the cell is going to be capable of primary active transport Should contain proteins if the cell is going to be capable of secondary active transport Should be made up of two layers of lipid molecules, oriented such that the hydrophilic parts face the extracellular and intracellular fluids Should exclude calcium ions Should allow for simple diffusion of cholesterol Should allow for simple diffusion of Vitamin D Will contain transporters for glucose Should have the characteristics of a kind of viscous fluid Should have a hydrophobic part between the two layers of the bilayer

Explanation / Answer

Vitamin D and cholesterol are hydrophobic molecules. Therefore, they can be transported through simple diffusion across cell membranes. All of the options seem to be correct.
