zhenek [66]

The correct answer is:  

Net Input: NADH, ADP, O₂

Net Output: NAD⁺, ATP, and H2O

Not Input or Output: Pyruvate, Glucose, Acetyl CoA, Coenzyme A and CO₂.

NADH together with FADH2 are reduced electron carriers that transfer their electrons and turn back into NAD+ and FAD.

Electrons are transferred to O2 and H2O is produced.  

ADP can be described as precursor for ATP synthesis, since it receives phosphate group for the formation of ATP. This process is possible thanks to H ions gradient and enzyme ATP synthase.
