WebLipid Metabolism Lipid catabolism (or lipolysis) refers to the process of triglycerides being broken down into glycerol and 3 fatty acids. Glycerol enters the glycolytic pathways and can be used to make a pyruvate. Fatty acids enter the mitochondria and are used to generate Acetyl CoA that can be used in the citric acid cycle. WebLipids in the diet can be _____. A. broken down into energy for the body B. stored as triglycerides for later use C. converted into acetyl CoA D. all of the above.

WebSince we lack those enzymes, the acetyl CoA is converted to ketone bodies to be transported to the brain as a usable respiratory substrate. Acetyl CoA cannot be turned into glucose via gluconeogenesis. If you look at where acetyl CoA enters the citric acid cycle, you’ll see that it happens BEFORE two decarboxylations. WebFats, known more formally as triglycerides, can be broken down into two components that enter the cellular respiration pathways at different stages.

WebMay 30, 2024 · Pyruvate then gets converted into Acetyl-CoA (a two carbon molecule) by an enzyme called pyruvatedehydrogenase after which it can enter the krebb's cycle. The problem is that there is no enzyme which does the opposite of pyruvatedehydrogenase, i.e. there's no enzyme which can convert Acetyl-CoA into pyruvate. WebBoth are 4-carbon molecules that can readily be converted back into acetyl-CoA by most tissues of the body, with the notable exception of the liver. Acetone is the decarboxylated form of acetoacetate which cannot be converted back into acetyl-CoA except via detoxification in the liver where it is converted into lactic acid , which can, in turn ...

WebGlyoxylate condenses with acetyl-CoA (a step catalyzed by malate synthase), yielding malate. Both malate and oxaloacetate can be converted into phosphoenolpyruvate, which is the product of phosphoenolpyruvate carboxykinase, the first enzyme in gluconeogenesis.
