Question

explain diffrent pathways of breakdown of gloucose in summary ?

Answer 1

in living organisms, the oxidation of glucose contributes to a series of complex biochemical reactions which provides the energy needed by cells. The first step in the breakdown of glucose in all cells is glycolysis, producing pyruvate which is the starting point for all other processes in cellular respiration. In cells where oxygen is present (aerobic respiration) these processes have been modeled in the TCA or Krebs cycle. A major part of the use of the energy from glucose oxidation is the conversion of ADP to ATP, with the energy-rich molecule ATP being subsequently used as the energy currency of the cell.
