Explain the difference between glycolysis, gluconeogenesis, glycogenolysis, and glycogen synthesis. Please note where each one occurs
What is the reason that amino acid degradation spikes approximately 24 hours after starting a fast? (A) The brain adapts to using ketone bodies, and amino acids serve as the primary precursors for ketone bodies.(B) Red blood cells begin using amino acids to drive their citric acid cycle.(C) Amino acids are broken down and used to replenish glycogen. (D) The liver needs to make glucose for brain and RBCs, and amino acids provide the carbon skeleton for gluconeogenesis.(E) The ammonia released from amino acid breakdown is a substrate for b-oxidation, which increases during prolonged fasting.
Starting with pyruvate (CH3COCOO—) as the precursor, the first step of gluconeogenesis is activation of pyruvate. Show the reaction for activation of pyruvate. Name the enzyme and coenzyme for this reaction. Why is the activation step necessary? What is the next step after the activation step?
What is the importance ofiron in diet? What is thedisease caused by irondeficiency?
Gluconeogenesis is like glycolysis but in reverse. Name the 4 enzymes that are responsible for this process. What is its final product?
In gluconeogenesis, only the carbon skeletons of amino acids, not fatty acids, are utilised. So how does fatty acid oxidation in the liver produce brain fuel? Describe the substances and routes involved.
What is the role of biotin in gluconeogenesis?
