What is produced during the first and second stages of aerobic respiration that are needed for the final stage (electron transfer phosphorylation)?
What will be an ideal response?
Glycolysis and the Krebs cycle provide reduced coenzymes (NADH and FADH2) which deliver electrons and hydrogen ions to the electron transfer chains in the inner mitochondrial membrane. This is ultimately needed to set up the hydrogen ion gradient and drive the flow of hydrogen ions through ATP synthases, which results in ATP formation.
