Which of the following is a reasonable explanation for why unsaturated fatty acids help keep any membrane more fluid at lower temperatures?Question 11Select one:a.The double bonds form kinks in the fatty acid tails, forcing adjacent lipids to be further apart.b.The double bonds block interaction among the hydrophilic head groups of the lipids.c.Unsaturated fatty acids permit more water in the interior of the membrane.d.The double bonds result in shorter fatty acid tails and thinner membranes.e.Unsaturated fatty acids have a higher cholesterol content and therefore more cholesterol in membranes.

What makes a fatty acid unsaturated?

Unsaturated fatty acids contain one or more bonds between carbon atoms in their long chains.

Which of the following makeup of cellular membranes would be most likely best suited to HOT temperatures?Question 6Select one:a.A higher proportion of saturated fatty acids.b.A higher proportion of saturated fatty acids and cholesterol.c.A higher proportion of unsaturated fatty acids.d.A higher proportion of unsaturated fatty acids and cholesterol.

Which of the following factors would tend to increase membrane fluidity?Group of answer choicesa greater proportion of relatively large glycolipids compared with lipids having smaller molecular massesa greater proportion of saturated phospholipidsa lower temperaturea relatively high content of peripheral proteins in the membranea greater proportion of unsaturated phospholipids

Which of the following facilitates the transit of fatty acids across the plasma membrane?Group of answer choicesbile saltschylomicronscarnitinealbuminfatty acid transport protein
