WebStep 1. In the first step of the citric acid cycle, acetyl \text {CoA} CoA joins with a four-carbon molecule, oxaloacetate, releasing the \text {CoA} CoA group and forming a six-carbon molecule called citrate. Step 2. In the … 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.

WebJun 2, 2024 · Through the process of phosphorylation, glycerol can be converted to glycerol-3-phosphate during the glycolytic pathway. When fatty acids are broken down into acetyl groups through beta-oxidation, the acetyl groups are used by CoA to form acetyl-CoA, which enters the citric acid cycle to produce ATP. WebThe glycerol can actually be converted into Glyceraldehyde-3-phosphate and then it completes the glycolytic reactions. The fatty acids are transported into the Mitochondria. Once in the Mitochondrial matrix, fatty acids are dismantled 2 carbons at a time and each 2 carbon piece is converted to Acetyl CoA. Acetyl CoA enters the Citric Acid Cycle.

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. The net result of the glyoxylate cycle is therefore the production of glucose from ...
