What is the ΔG°’ for the complete oxidation of the acetyl unit of acetyl CoA by the citric acid cycle?

Glucose 6-phosphate is in a pivotal position in metabolism. Depending on conditions, glucose 6-phosphate follows one of several pathways. Under what conditions do the following occur?(a) Glycolysis(b) Hydrolysis to free glucose(c) Pentose phosphate pathway(d) Glycogenesis

Anabolism of protein need ATP, NADH and NADPH. * O True O False

Under conditions of starvation, acetyl-CoA, instead of being degraded in the citric acid cycle, is converted to acetone and 3-hydroxybutyrate, compounds called ketone bodies that the brain can use as a temporary fuel. Show how the ketone bodies are formed.

The following reaction constitutes the first step in the citric acid cycle. List all the reactants in this reaction? H₂O COO™ C=O || CH3-C-CoA Acetyl COA CH₂ COO™ Oxaloacetate HS-COA Citrate synthase O Citrate and HS-COA COO™ I CH₂ HO-C-COO CH₂ COO™ Citrate Water, Acetyl CoA, and HS-CoA O Oxaloacetate and Acetyl CoA Oxaloacetate, Acetyl CoA, and HS-COA O Oxaloacetate, Acetyl CoA, and Water

Acyl-CoA synthase is the enzyme that activates a fatty acid by converting it to a fatty acyl-CoA in a series of two reactions. In the first reaction, the fatty acid reacts with ATP and one of the products formed is ADP. The other product reacts in a second reaction with CoASH to form the fatty acyl-CoA. Propose a mechanism for each of the reactions.
