Doctor my dad passed out wile running the marathon. why?
Well it might seem that he didn't get enough oxygen. he probably ran out of ATP.
ATP is an energy source made in the mitochondrion through a series of process.
* Hes so annoying *
Well the process starts with something called glucose,then the glucose electrons lose their hydrogen bonds then go through glycolosis this happens in the cytoplasm . The outcome is 2 pyruvate that gets transported into the mitochondrion which goes through pyruvate oxidation where the pyruvate acid turns pyruvate to NADH. From there NADH gets transported into the Krebs cycle.
From the Krebs cycle the energy is used to send molecules to the electron transport chain. Their the electrons would be used to reel in some atoms that will make ATP. The products of cell respiration are 32 ATP, ADP, NAD+ and phosphate p. the ATP before being used has to go through ATP synthase.
I think he's American.
The process is all done automatically when you breath in oxygen and exhale carbon dioxide. also to feed the energy you need water and food. kinda like photo synthases
