Which of the following lipoproteins is responsible for carrying
cholesterol from peripheral tissues (i.e skeletal muscle) back to the
liver? ANSWER: HDL
⫸ What is the primary role of LCAT (Lecithin-cholesterol
acyltransferase)? ANSWER: To esterify cholesterol transported by
HDL
⫸ Which enzyme is responsible for transferring triacylglycerol from
VLDL to HDL in exchange for cholesterol? ANSWER: LCAT
(Lecithin-Cholesterol Acyltransferase)
⫸ Which of the following lipoproteins is responsible for the transport
of dietary triacylglycerols in the blood? ANSWER: Chylomicrons

synthesized triacylglycerols in the liver will be packaged into which
of the following lipoproteins? ANSWER: VLDL
⫸ When LDL is taken up by a cell, it will have which of the
following impacts to intracellular cholesterol? ANSWER: Increase in
intracellular cholesterol; Decrease on de novo cholesterol synthesis
, ⫸ Which of the following apoproteins is required for activation of
lipoprotein lipase? ANSWER: ApoCII

present on VLDLs? ANSWER: ApoB100; ApoCII; ApoE
⫸ Which of the following lipoproteins contains ApoA and ApoCII?
ANSWER: HDL

and can potentially be used as fuel by all of the following tissues
except: ANSWER: liver
⫸ High levels of acetyl CoA within the mitochondria will stimulate
the activity of which of the following enzymes? ANSWER: Pyruvate
carboxylase
⫸ When citrate is shuttled out of the mitochondria for fatty acid
synthesis, the initial reaction by citrate lyase generates which of the
