Question

Biological membranes are semipermeable: Some molecules are able to enter easily, but others are not. Sort these molecules or ions depending on their method of crossing biological membranes. Note that some of these examples may also pass through a membrane by an active transport process. However, this question asks only about passive transport processes. Simple Diffusion fatty acids steroid hormones O2 Facilitated Diffusion nucleosides K+ At least one item has been sorted incorrectly. Molecules that are too large or that are hydrophilic move across the membrane by facilitated diffusion. Which item is an example of a nonpolar, but large molecule?

Explanation / Answer

Simple diffusion: O2 and steroid hormone Facilitated diffusion: fatty acid, nucleoside, K+
