Organ-Specific Metabolism | Systemic Metabolism Part 1 | Macronutrients Lecture 30

The liver, muscle, brain, and adipose tissue all play their own give and take when it comes to metabolism.

The liver is a master regulator in metabolism. The liver can perform glycogenesis, glycogenolysis, gluconeogenesis, lipogenesis, ketogenesis, protein synthesis especially for plasma proteins, deamination, and urea synthesis. The liver primarily uses fatty acids as fuel, but can also use glucose and amino acids. The brain requires glucose for fuel and CANNOT use fat, though it can adapt to ketones. The muscle can perform glycogenesis and glycogenolysis, however it is rather selfish and would keep all the glucose released from glycogen for itself. Muscle can use glucose, fatty acids, or ketones as fuel, but primarily uses fatty acids at rest and glucose when exercising. Muscle can activate the lactic acid system during high intensity activity. The adipose (fat) tissue can perform lipolysis, lipogenesis, and acts as the major site for triglyceride storage. Adipose primarily uses glucose as fuel, but can also use fatty acids.
