Answer #1

Fatty acids are major fuel source for human body; both at rest and during exercise.

Triglycerides stored within the adipose tissue and within the muscle fiber is known to be the main source of free fatty acids during exercise.

Plasma free fatty acids(FFA), although present in micromolar concentrations, are the major circulating lipid fluid.

Intense exercise increase the amount of plasma free fatty acid inside the blood manyfolds.

The concentration of free fatty acid inside the blood is hormone- mediated process.

Glucagon act as stimulating factor for the release of fatty acids from stored triglycerides in adipose tissue and insulin inhibits this process.

    26. Why did Jessie’s carnitine deficiency cause her to have abnormally low plasma glucose levels at the end of a fasting study, when compared to a healthy person who has fasted for the same length of time? In the absence of carnitine, the liver stores large amounts of glycogen; absorption of glucose to create these stores depletes blood glucose Carnitine acts as a hormone and stimulates glucose release from the liver; lack of carnitine results in loss of hepatic glucose...
