What is the difference between oxidative phosphorylation and aerobic glycolysis in terms of energy production in cells?
Oxidative phosphorylation produces more energy in cells compared to aerobic glycolysis. Oxidative phosphorylation occurs in the mitochondria and involves the electron transport chain, while aerobic glycolysis takes place in the cytoplasm and produces energy through the breakdown of glucose.

What are the key differences between aerobic glycolysis and oxidative phosphorylation in terms of energy production in cells?
Aerobic glycolysis produces energy quickly but in small amounts, while oxidative phosphorylation produces energy more slowly but in larger amounts. Aerobic glycolysis occurs in the cytoplasm and does not require oxygen, while oxidative phosphorylation occurs in the mitochondria and requires oxygen.
Why do cancer cells prefer to use glycolysis for energy production instead of oxidative phosphorylation?
Cancer cells prefer to use glycolysis for energy production instead of oxidative phosphorylation because glycolysis is a faster way to generate energy, allowing cancer cells to grow and divide rapidly. Additionally, glycolysis can occur in low-oxygen environments, which are common in tumors.
If a biocide were to block ATP production other than from glycolysis what would be the net ATP output?
If a biocide were to block ATP production from processes other than glycolysis, such as oxidative phosphorylation in the mitochondria, the net ATP output would likely decrease significantly. ATP production in glycolysis is relatively modest compared to oxidative phosphorylation, so blocking the latter would substantially reduce overall ATP generation in the cell. This disruption could greatly impact cellular functions dependent on ATP availability.
How many ATP molecules are produced by oxidative phosphorylation for each glucose that enters glycolysis?
Approximately 30-32 molecules of ATP are produced by oxidative phosphorylation for each glucose molecule that enters glycolysis.
Different between oxidative phosphorylation and substrate level phosphorylation?
Substrate-level phosphorylation occurs during Glycolysis and the Kreb's Cycle and involves the physical addition of a free phosphate to ADP to form ATP. Oxidative phosphorylation, on the other hand, takes place along the electron transport chain, where ATP is synthesized indirectly from the creation of a proton gradient and the movement of these protons back accross the membrane through the protein channel, ATP synthase. As the protons pass through, ATP is created.

What portion of aerobic respiration requires oxygen?
glycolysis, Krebs cycle, oxidative phosphorylation
How many ATP molecules are produced by oxidative phosphorylation for each glucose that enters glycolysis?
Approximately 30-32 molecules of ATP are produced by oxidative phosphorylation for each glucose molecule that enters glycolysis.
Pathway of cellular respiration?
glycolysis, Krebs cycle, electron transport chain, oxidative phosphorylation
What advantages does oxidative phosphorylation have over anaerobic glycolysis?
Both processes are run inside the human body in order to produce energy. Oxidative phosphorylation produces much more energy at a less of an expense than anaerobic glycolysis. It also has energy coming from multiple sources unlike anaerobic glycolysis which only comes from one source.
What generates the most ATP of cellular respiration?
Oxidative Phosphorylation [Chemiosmosis and ETC]
What are the two stages of cellular respiration?
The two stages of cellular respiration are glycolysis and oxidative phosphorylation. Glycolysis occurs in the cytoplasm and breaks down glucose into pyruvate. Oxidative phosphorylation takes place in the mitochondria and involves the electron transport chain and ATP synthase to generate ATP using the energy from electron carriers.
Substrate level phosphorylation accounts for approximately what percentage of ATP formed during glycolysis?
100%. Substrate level phosphorylation accounts for about 10% of ATP generated by respiration. The other 90% is generated by oxidative phosphorylation.
What are the four possible energy sources for a muscle and the three sources of ATP for muscle contraction?
Creatine phosphate, oxidative phosphorylation, and glycolysis.
