Question

part d - oxidative phosphorylation 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
ot input or output\ bin. (note that not all of the inputs and outputs of oxidative phosphorylation are listed.) view available hint(s) net input net output not input or output o₂ co₂ nad⁺ adp coenzyme a glucose nadh atp pyruvate water acetyl coa reset help

Explanation:

Step1: Recall oxidative phosphorylation inputs

Oxidative phosphorylation uses $NADH$, $FADH_2$ (not shown here), $O_2$, and $ADP + P_i$. So net - inputs are $O_2$, $ADP$, $NADH$.

Step2: Recall oxidative phosphorylation outputs

The main outputs are $ATP$, $H_2O$ and $NAD^+$. So net - outputs are $ATP$, $H_2O$, $NAD^+$.

Step3: Identify non - relevant molecules

Glucose is used in glycolysis before oxidative phosphorylation, pyruvate is a product of glycolysis and enters the citric acid cycle before oxidative phosphorylation, acetyl - CoA is involved in the citric acid cycle, and coenzyme A is a general co - factor in many metabolic reactions not directly an input or output of oxidative phosphorylation. So not input or output are glucose, pyruvate, acetyl - CoA, coenzyme A.

Answer:

net input: $O_2$, $ADP$, $NADH$
net output: $ATP$, $H_2O$, $NAD^+$
not input or output: glucose, pyruvate, acetyl - CoA, coenzyme A
