Final answer:
D. Lipase
The name of the enzyme that breaks down triglycerides in VLDL and chylomicrons in the capillaries is lipoprotein lipase.
Step-by-step explanation:
The enzyme that is located in the capillaries and breaks down triglycerides in VLDL (Very Low-Density Lipoprotein) and chylomicrons is known as lipoprotein lipase. This enzyme plays a critical role in lipid metabolism by hydrolyzing triglycerides into free fatty acids and glycerol, which can then be used by cells for energy or stored in adipose tissue as fat. After lipoprotein lipase action, the remnants of chylomicrons are taken up by the liver, where they are further processed for elimination or repackaged for transport as different lipoproteins.
