A scientist compares the plasma membrane compositionof an animal from the Mediterranean coast with one fromthe Mojave Desert. Which hypothesis is most likely to becorrect?a. The cells from the Mediterranean coast animal willhave more fluid plasma membranes.b. The cells from the Mojave Desert animal will have ahigher cholesterol concentration in the plasmamembranes.c. The cells’ plasma membranes will beindistinguishable.d. The cells from the Mediterranean coast animal willhave a higher glycoprotein content, while the cellsfrom the Mojave Desert animal will have a higherlipoprotein content.

The presence of cholesterol in the plasma membranes of some animals Group of answer choices A. makes the membrane less flexible, allowing it to sustain greater pressure from within the cell B. enables the animal to add hydrogen atoms to unsaturated phospholipids C. makes the animal more susceptible to circulatory disorders D. enables the membrane to stay fluid more easily when cell temperature drops E. enables the animal to remove hydrogen atoms from saturated phospholipids

Phospholipids and cholesterol must be transported from their site of synthesis to various membrane systems within cells. One way of doing this is through vesicular transport, as is the case for many proteins in the classic secretory pathway (see Chapter 14). However, phospholipid and cholesterol membrane-to-membrane transport in cells does not occur solely by vesicular transport. What is the evidence for this statement? What appear to be the major mechanisms for phospholipid and cholesterol transport?
