The glyoxylate cycle, a variation of the tricarboxylic acid cycle, is an anabolic pathway occurring in plants, bacteria, protists, and fungi. The glyoxylate cycle centers on the conversion of acetyl-CoA to succinate for the synthesis of carbohydrates. [1] In microorganisms, the glyoxylate cycle allows cells to use two carbons ...
WebFeb 5, 2024 · Later, the acetyl CoA is completely oxidized into CO 2 and H 2 O by entering the citric acid cycle. This pathway follows glycolysis in aerobic organisms and plants. 2. Lactic acid fermentation. In conditions where the oxygen is insufficient, like in the skeletal muscle cells, the pyruvate cannot be oxidized due to lack of oxygen. WebAug 7, 2024 · The tricarboxylic acid cycle (TCA cycle), also known as the citric acid cycle or the Krebs cycle, is a major energy-producing pathway in living bodies. Cells obtain ATP from breakdown of glucose in the absence of oxygen as in glycolysis. However, most organisms normally are aerobic and oxidize their organic fuels completely to CO2 and …
