What is the role of atp synthase in cellular respiration?
it produce ATP witch is the very point of the respiration
Through respiration, there are a lot of chemical reaction (called the Citric acid cycle or Krebs cycle)that use glucose and oxygen to produce ATP wich is the molecule used as energie by most organism's cells.
the atp synthase combine the adenosine diphosphate (ADP) with a phosphate molecule in order to form an ATP adenosine triphosphate.
