Which of the following pathways provides the primary oxidizable fuel for skeletal muscle in the fasted state? correct answer: Lipolysis from adipose tissue In the fasted state the skeletal muscle is predominantly oxidizing free fatty acids. These are provided through the process of lipolysis in the adipose tissue. Triacylglycerols stored in the adipose are hydrolyzed to free fatty acids and transported bound to albumin in the blood stream. In the fasted state, both the liver and the skeletal...
