We know that cellular levels of NAD+ are in a constant state of flux - as our cells create and use energy, so too our cells create and use NAD+. NAD+ levels can fluctuate or decline because of changes in the absolute amount of NAD+/NADH or shifts in the NAD+/NADH ratio. Our ...
What is the significance of NAD+ in fermentation and cell respiration? Why is fermentation necessary under anaerobic conditions? Why does a cell perform fermentation if it does not produce any ATP energy for the cell? Why do cells need fermentation to continue glycolysis?
Why does the Krebs cycle need oxygen? How does the electron transport chain change when NADH and FADH2 donate their electrons to complex 1 or 2? Do they become hydrolyzed? How many molecules of NADH are produced during glycolysis? How m...
It means that if we had 10 moles of ATP, we could synthesize ten more, only after consuming the initial lot. So, our body is constantly striking a balance between the amount it blows up and the amount it has stored in. The catch is, we store around 50 grams of it, while we end ...
In steroid hormone synthesis, placenta mitochondria need the presence of NADH in order to have a functioning cholesterol side-chain cleavage enzyme system [173]. 8.5. Selenium and coenzyme Q10 (CoQ10) We consider that the main place for selenium in body functions is in its protective property ...

Why do cells need both respiration and fermentation to breakdown glucose? Why do most organisms use aerobic cellular respiration (36ATP/glucose) rather than fermentation (2ATP/glucose) to supply their energy needs? What is the total amount of ATP produced by cellular respirati...
Why is NADH used in gluconeogenesis? Explain respiration, glycolysis of the Krebs cycle Do plants perform cellular respiration? Explain why or why not. How is cellular respiration impacted by the vascular cambium?Explore our homework questions and answers library Search Browse...
How do oxidation and reduction reactions correlate to energy flow in cells? Describe what is being oxidized and reduced in cellular respiration (OIL RIG: Oxidation is Loss; Reduction is Gain in electrons) Which kind of reaction converts NAD^+ to ...
1. NAD+-Fueling Pathways and Cancer Progression The nicotinamide adenine dinucleotide (NAD+) and its reduced form (NADH) play a determinant role in maintaining cellular metabolism and cell survival. NAD+ serves as an electron acceptor essential for fatty acid oxidation, glycolysis and the TCA ...
