Various characteristics of the lipids in a membrane contribute to its fluidity-- which in turn determines how easily molecules can diffuse into and out of the cell across the membrane. Which of the following statements about this topic are correct?
A. Longer fatty acid tails of phospholipids make the membrane less fluid, thus slowing diffusion.
B. A higher concentration of saturated fatty acid tails of phospholipids makes the membrane less fluid, thus slowing diffusion.
C. At ambient temperatures (temperatures typically found in a cell), cholesterol stiffens the membrane, reducing fluidity and diffusion.
D. A higher concentration of unsaturated fatty acid tails of phospholipids makes the membrane less fluid, thus slowing diffusion.
