In adipose tissue, lipoprotein lipase:
a. Forms triacylglycerol from circulating free fatty acids and glycerol
b. Is activated in response to norepinephrine released from synapses upon fat cells
c. Is synthesized by fat cells and delivered to capillary endothelial cells
d. Signals fat cells to form endocytic vesicles for the ingestion of fat
e. Travels from fat depots to the hypothalamus and functions as a signal of adiposity
ANS: C
Transfer of this enzyme from fat cells to capillaries allows the cleavage of blood-borne triacyl-glycerides into molecules (glycerol, fatty acids) that are more easily absorbed into fat cells. See 3-17.
