● Q, just like the Q in photosynthesis, is involved in the electron transport chain

also. Q takes the energy from FADH2, reducing it to FAD. Q then adds FADH2's

energy to the chain, sending it down to cytochrome a3, so that more O2, then H2O,

is produced. And that is the electron transport chain

● But where are those 34ATPs that is supposed to be charged?

Remember that the electron transport chain occurs in the inner membrane of the

mitochondria. Well, this membrane also houses a protein called ATP synthase, which

+
does nothing but produces ATP. H pumped by the electron transport chain is used to
power the synthesis of ATP.

● ATP synthase is plugged into the electron transport chain, producing 34 ATP

from the NADH and FADH2 that the electron transport chain got from the Krebs cycle

and glycolysis.

● The Krebs cycle made 2ATP, NADH, and FADH2. Glycolysis made 2 ATP

and NADH from glucose. That is the Aerobic Respiration.
