Which one of the following statements is INCORRECT regarding the process of lipolysis in adipocytes and fat oxidation in target cells?Question 17Select one:a.Hormone-sensitive lipase (HSL) enzyme breaks down triglycerides into their free fatty acid (FFA) and glycerol components.b.Liberated FFAs enter the Krebs cycle as acetyl CoA through beta oxidation.c.Epinephrine is released during high blood glucose levels to trigger lipogenesis in adipocytes.d.Beta oxidation involves cutting two carbon fragments from the end of the FFA chain.e.Liberated glycerol enters the glycolysis pathway as glyceraldehyde-3-phosphate (G3P).

Which one of the following statements is INCORRECT? Question 5Select one:a.During exercise or fasting, inhibition of the pyruvate dehydrogenase enzyme allows us to burn fat while preserving our limited carbohydrate reserves.b.Insulin can inhibit ketogenesis by inhibiting the carnitine carrier protein located on the mitochondrial membrane.c.In adipocytes, insulin signalling allows excess acetyl CoA to leave the mitochondria to enter the lipogenesis pathwayd.The enzyme glucose-6-phosphatase (G6Pase) in skeletal muscle cells allows the cell to produce glucose for export into the bloodstream during hypoglycaemia.e.Insulin promotes the insertion of the GLUT4 transporter protein into the cell membrane through the phosphatidylinositol (PI) pathway.

Which one of the following statements is INCORRECT about the events that occur when glucose enters a hepatocyteQuestion 14Select one:a.Insulin inhibits lipolysis.b.Glucose enters the hepatocyte through the GLUT2 transporter protein.c.Excess acetyl CoA can enter the lipogenesis pathway.d.Insulin receptor activation inhibits enzymes that allow glucose oxidation through glycolysis and the Kreb’s cycle.e.Glucose is converted into glucose-6-phosphate (G6P), glucose-1-phosphate (G1P), then glycogen because insulin receptor activity activates glucokinase and glycogen synthase enzymes, respectively.
