[Answer] In cellular respiration most energy is released and transferred to ATP when _____.

Answer: high-energy electrons “fall” to lower energy levels
In cellular respiration most energy is released and transferred to ATP when _____.
Aerobic respiration requires oxygen (O2) in order to create ATP. Although carbohydrates fats and proteins are consumed as reactants aerobic respiration is the preferred method of pyruvate breakdown in glycolysis and requires pyruvate to the mitochondria in order to be fully oxidized by the citric acid cycle. The products of this process are carbon dioxide and water and the energy transferred is used to break bonds in ADP to add a third phosphate group to form ATP (adenosine triphosphate) by substrate-level phosp…
ATP synthase then uses the energy stored in this gradient to make ATP. This process is called oxidative phosphorylation because it uses energy released by the oxidation of NADH and FADH2 to phosporylate ADP into ATP. In plants. The light reactions of …

The overall process of glycolysis is: Glucose + 2 NAD + 2 ADP + 2 Pi → 2 pyruvate + 2 NADH + 2 H + 2 ATP If glycolysis were to continue indefinitely all of the NAD would be used up and glycolysis would stop. To allow glycolysis to continue organisms must be able to oxidize NADH back to NAD . How this is performed depends on which external electron acceptor is available.
A core set of energy -producing catabolic pathways occur within all living orga…
