Final answer:
Lipoprotein lipase recognizes ApoC-II, which is the specific apolipoprotein that activates LPL for the hydrolysis of triglycerides in chylomicrons and VLDL.
Step-by-step explanation:
Lipoprotein lipase (LPL) is an enzyme that plays a crucial role in lipid metabolism by hydrolyzing the triglycerides present in chylomicrons and very low density lipoproteins (VLDL). This process requires recognition of specific Apo proteins on the surface of these lipoproteins. LPL specifically recognizes ApoC-II as its co-factor, which activates the enzyme to initiate the hydrolysis of triglycerides.
Regarding the question, "Which Apo protein does LPL recognize?" the correct answer is (c) ApoC-II. It is important to note that LPL interaction with ApoC-II is essential for the efficient metabolism of triglyceride-rich lipoproteins. Dysfunctional or deficient LPL activity can lead to conditions like hyperlipoproteinemia type I, where there's an accumulation of chylomicrons due to impaired triglyceride breakdown.
