when glucose goes into a cell it comes out as Co2 (carbon dioxide)
Once glucose enters the cell, it undergoes glycolysis and subsequent metabolism to produce ATP, the energy currency of the cell. Glucose can also be stored as glycogen for future energy use. Entry into cells is mediated by transport proteins, and phosphorylation within the cell ensures glucose retention for metabolism. ;
After glucose enters the cell, it is phosphorylated to trap it inside and then undergoes glycolysis, where it is converted to pyruvate, producing ATP as a result. The pyruvate can further enter pathways for more energy production or be converted into glycogen for storage. This process is essential for the energy needs of the cell.
