Lipid Production: a. are produced in the small intestine and exported to the lym

Question

Lipid Production:

a. are produced in the small intestine and exported to the lymphatic system

b. bind SRB1 receptors that transports cholesterol esters from LDL particles into the cell

c. will undergo less endocytosis in hepatic and extrahepatic tissues that have increased levels of SCAP and SREBP in the golgi

d. None of the above

Endogenous transport:

a. begins in the small intestine and ends at the liver

b. begins with the production of chylomicrons that are subsequently reduced to “remnants” and undergo endocytosis by the liver

c. ends when LDL particles bind to the SR-B1 receptor on the liver cell

d. is a means for transporting cholesterol and TAG from the liver to other tissues in the body

TAG production:

a. requires acyl-CoA production that utilizes a single ATP equivalent

b. requires glycerol-3-phosphate whose production will decrease in the adipose tissue due to decreased expression of the GNG enzyme PEPCK

c. will only occur in the liver

d. occurs in the liver and will be subsequently packaged in chylomicron particles and shipped to the rest of the tissues

Explanation / Answer

1) the main function of the lipids is binds to the SRB1 receptor which basically transport the ester LDL into the cells.. In this way the cholesterol are transported inside the body . The correct option is (b)

2) endogenous transport is a type of transport which begins in the liver where they synthesis the lipoprotein . It is process which results in the transport of the TAG and cholesterol inside the body.. The correct option is option (d)
