In the last stage of cellular respiration, oxidative phosphorylation, all of the reduced electron carriers produced in the previous stages are oxidized by oxygen via the electron transport chain. the energy from this oxidation is stored in a form that is used by most other energy-requiring reactions in cells. from the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of oxidative phosphorylation. drag each compound to the appropriate bin. if a compound is not involved in oxidative phosphorylation, drag it to the "not input or output" bin. (note that not all of the inputs and outputs of oxidative phosphorylation are listed.)

(glucose, co2, o2, atp, adp, had, hadh, h2o, coenzyme a, pyruvate, acetly coa )

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.
