Lipids Often Move Within the Body in Complexes Known as Lipoproteins;

question 43

Multiple Choice

Lipids often move within the body in complexes known as lipoproteins; what advantage does this strategy provide?

• A) Lipids alone have high solubility in body fluids and would be difficult to transport.
• B) With a protein component as an identifier, cells needing lipids can use membrane receptors and acquire only as much lipid as they need at any given moment.
• C) Rather than simply diffusing into adjacent cell membranes as free lipids would do, surplus lipoproteins can be routed to the kidneys for disposal or modification.
• D) Lipids associated with lipoproteins are more likely to be able to pass freely through the cell membrane.
