Glycolysis - Wikipedia

WebbThe process of glycolysis involves many intermediate steps, but can be summarised by four key events: 1. Phosphorylation A hexose sugar (typically glucose) is phosphorylated by two molecules of ATP (to form a hexose bisphosphate) This phosphorylation makes the molecule less stable and more reactive, and also prevents diffusion out of the cell 2. WebbGlycolysis can be divided into two phases: energy consuming (also called chemical priming) and energy yielding. The first phase is the energy-consuming phase, so it requires two ATP molecules to start the reaction for each molecule of glucose. However, the end of the reaction produces four ATPs, resulting in a net gain of two ATP energy molecules. infor103

WebbBoth plants and animals carry out the process of respiration, but only plants proceed to another process called ‘photosynthesis‘. The process of glycolysis begins in the cytoplasm of the cells and is completed in the mitochondria as you can see in the diagram given above. The simple sugar molecules are broken down to energy or ATP molecules.
