Where does the second water come from ? I get that the first one comes in the conversion of citrate to isocitrate, but where does 2nd one come in? thanks
The Glyoxylate cycle is a metabolic pathway found in certain microorganisms and plants. It allows for the conversion of two-carbon compounds, such as acetyl-CoA, into four-carbon compounds, which can then be used as building blocks for other molecules.
The Glyoxylate cycle is similar to the TCA cycle in that it involves the conversion of acetyl-CoA into other molecules. However, the Glyoxylate cycle bypasses two steps in the TCA cycle, allowing for the net production of four-carbon compounds instead of the usual two-carbon compounds.
The Glyoxylate cycle can be found in certain bacteria, fungi, and plants. It is also present in some animals, such as nematodes, that lack the TCA cycle.
The Glyoxylate cycle allows for the production of glucose or other sugars from acetyl-CoA. This is important for organisms that cannot obtain glucose from their environment, such as plants and bacteria living in low-nutrient environments.
The Glyoxylate cycle does not directly produce ATP, the main energy currency of cells. However, it can indirectly contribute to energy production by providing building blocks for other metabolic pathways that do produce ATP, such as the TCA cycle and oxidative phosphorylation.
