Detailed explanation-1: -The second half of glycolysis is known as the pay-off phase, characterised by a net gain of the energy-rich molecules ATP and NADH. Since glucose leads to two triose sugars in the preparatory phase, each reaction in the pay-off phase occurs twice per glucose molecule.
Detailed explanation-2: -The second half of glycolysis (also known as the energy-releasing steps) extracts energy from the molecules and stores it in the form of ATP and NADH, the reduced form of NAD.
Detailed explanation-3: -Glycolysis takes place in the cytosol of a cell, and it can be broken down into two main phases: the energy-requiring phase, above the dotted line in the image below, and the energy-releasing phase, below the dotted line. Energy-requiring phase.
