Final answer:
D. Chylomicron is the lipoprotein that transports diet-derived lipids. Chylomicrons carry dietary triacylglycerols through the bloodstream to the liver, where they are either used for energy or stored as fat.
Step-by-step explanation:
The lipoprotein that transports diet-derived lipids is D. Chylomicron. Chylomicrons are responsible for the transportation of lipids from the digestion process into the bloodstream and eventually to the liver. They have the highest lipid to protein ratio, which results in the lowest density among the lipoprotein classes, and they specifically carry dietary triacylglycerols through the bloodstream. When chylomicrons encounter the enzyme lipoprotein lipase, the triacylglycerols are broken down into fatty acids and glycerol, which can then be used for energy or stored in adipose tissue as fat.
In contrast, Very Low-Density Lipoproteins (VLDL) transport newly synthesized triglycerides from the liver to the tissues, Low-Density Lipoprotein (LDL), often referred to as "bad cholesterol", carry cholesterol from the liver to other tissues, and High-Density Lipoprotein (HDL), known as “good cholesterol,” collect cholesterol from other tissues and return it to the liver.
