Which molecule loses electrons in a cellular respiration?

In cellular respiration, glucose is the molecule that loses electrons. During the process, glucose undergoes oxidation, which involves the removal of electrons as it is broken down into carbon dioxide and water. This loss of electrons is coupled with the reduction of other molecules, such as NAD+ and FAD, which gain the electrons and become NADH and FADH2, respectively. This transfer of electrons is a key part of the energy extraction process in cellular respiration.
