WebGlycolysis 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. WebSo over here, this is a glucose molecule over here, you see one, two, three, four, five, six carbons.
