What is the common end-product of the catabolism of the branched chain amino acids that are converted to succinyl CoA? alpha-ketoglutarate glyceraldehyde phosphate oxaloacetate

Pyruvate dehydrogenase complex and α -ketoglutarate dehydrogenase complex are huge enzymes consisting of three discrete enzymatic activities. Which amino acids require a related enzyme complex, and what is the name of the enzyme?

What enzyme(s) is/are specifically required for the oxidation of a Aeven monounsaturated fatty acid? (select all that apply) O Methylmalonyl CoA Mutase O enoyl-CoA Hydratase 43-enoyl-CoA isomerase Thiolase 2,4-Dienoyl-CoA Reductase OPropionyl-CoA carboxylase

How many acetyl-CoA molecules can be produced from a 20-carbon chain free fatty acid?

Pyruvate can be converted to glucose via gluconeogenesis, or it can be oxidized to acetyl-CoA for energy production. The enzyme pyruvate carboxylase is regulated allosterically by which of the following? Oxaloacetate All of the above Acetyl COA Glucose-6-phosphate Fructose-6-phosphate

In the first step of the TCA cycle the acetyl group of acetyl-CoA is transferred to oxaloacetate to produce citrate. Where will the carbonyl carbon of that acetyl group be after the first CO2 is expelled? Group of answer choices The first carbon of α-ketoglutarate The last carbon of α-ketoglutarate The fourth carbon of α-ketoglutarate The third carbon of α-ketoglutarate

What is the final fate of the carbons in acetyl-CoA after several turns of the citric acid cycle?

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.

Why are the symptoms of carnitine palmitoyl transferase II deficiency more severe during fasting?

What is the name of the enzyme that produces acetyl-CoA? What is the name of its major inhibitor?   If this inhibitor is active, how will carbohydrate metabolism be affected?  Be specific.  (The word metabolism isn’t specific.)
