Mobilization of fatty acids from adipose tissue during exercise is largely due to:Group of answer choicesβ-adrenergic stimulationdecreased glucagonincreased insulin

During exercise of increasing intensity there is a greater reliance on muscle glycogenolysis due to local factors and increased levels of this hormone:Group of answer choicesadrenalineinsulinglucagon

The greater liver glucose output during exercise is due primarily to:Group of answer choicesincreased glycogenolysisreduced hepatic glucose extractionenhanced gluconeogenesis from lactate

Which of the following is true about fatty acid usage for energy?Multiple ChoiceEnergy is released from fatty acids anaerobically.Energy is released from fatty acids in a process called lipogenesis.Gram for gram, fatty acids provide more than twice as much energy as glucose.  Fatty acids are useful for intense exercise.

As exercise intensity increases, there is a progressive increase in the reliance of carbohydrate metabolism in the exercising skeletal muscles. This observation is described as the

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.
