    Glycolysis: Allosteric Regulation of PFK-1

    This podcast covers the allosteric regulation of Phosphofructokinase 1( PFK-1). A key allosteric activator is F2,6 bis-phosphate, which is produced by PFK-2 in the well-fed state. The production of this molecule is increased by the dephosphorylation of PFK-2, the enzyme responsible for its production. insulin will activate this enzyme by promoting g its dephodphorylation.Thus resulting in higher levels of F2, 6 bis-phosphate in the cytoplasm and resulting in the activation of PFK-1 and Glycolysis.

    Classification of Amino Acids

    Amino acids can be classified as essential or non- essential. They can also be classified by the carbon skeletons they produce during catabolism. These carbon skeletons can be either glucogenic or ketogenic.

    A Summary of Metabolism & Its Regulation

    A Summary of Metabolism & Its Regulation :This podcast summarizes metabolism and its regulation by hormones. It includes: 1. Definition of metabolism, catabolism, anabolism, and their cellular compartments; 2. The 3 stages of catabolism; 3. The major cellular uses of glucose, amino acids, fatty acids, and cholesterol; 4. The major metabolic pathways that produce energy from dietary carbohydrates and fat; 5. Comparison of the energy (ATP) output from catabolism of glucose , fatty acids, and acetoacetate (ketone bodies); 6. Hormonal regulation of the major metabolic pathways by insulin, glucagon, and epinephrine

    Integration of Metabolism: A Summary of Tissue Metabolism

    This podcast covers the major tissue effects of insulin and glucagon in the well-fed state and the fasting state, respectively. The key effects of these hormones on carbohydrate, fat, and protein metabolism in various tissues are summarized.

    Cell-Cell Communication

    Cell-Cell Communication is a fundamental process that is essential for the regulation of metabolism in various organs. Through hormones of the endocrine system, signals are chemically transmitted through the bloostream between different organs. The outcome of a hormone binding its specific receptor in target tissues can produce profound effects on metabolism. Insulin and its effects on the liver, is used as an example of the outcome of communication between the pancreas and the liver.

    Catabolism of Alanine, Glutamate & Aspartate

    This podcast covers the catabolism of alanine, glutamate and aspartate, including the roles of 3 important enzymes alanine transaminase (ALT), aspartate transaminase (AST) and glutamate dehydrogenage in this process. Input of nitrogen into the Urea cycle is provided directly or indirectly through the metabolism of the 3 discussed amino acids.
