I asked this question before I still don't get it. Using Flutter ver 3.3.2 

Return value is missing see attachment on the bottom of this page.

Here is the full code and the screenshot below the full code. Also when putting in the answer can you put in the full code. Because I put in the previous answers I still got error messages.

Explain the role, positioning, mobility and contribution to the proton gradient of the stand-alone molecules and individual complexes of the mitochondrial electron transport chain

Explain the role of the components in the Q cycle in complex III: Cytochromes, ubiquinone and ubiquinol, iron-sulfur centers, NADH, FADH2

Please help me answer this question.

In glucose metabolism, glucose enters into the Glycolysis pathway. The products of glycolysis are then utilized by the Pyruvate Dehydrogenase Complex, which shuttles its products into the Citric Acid Cycle. The combined activities of these pathways directly synthesize a number of molecules of ATP, GTP, NADH and FADH₂. Indicate the net gain of each of the molecules listed in the table below if a single glucose molecule were to be completely and sequentially metabolized by all three processes.
