Why does the Krebs cycle occur in aerobic cellular respiration? Why is a different enzyme involved in each step of glycolysis? How are NADH and NAPDH similar? What role does NADH play in cellular respiration? Why is oxygen needed for oxidative phosphorylation?
Why does the Krebs cycle occur in aerobic cellular respiration? Why does cellular respiration not produce a unifrom amount of ATP? When ATP releases some energy, it also releases inorganic phosphate. What purpose does this serve in the cell? A. It can only be used to generate more ATP B....
» The Krebs Cycle begins with pyruvate, and as we have two molecules of pyruvate here, the net ATP gain there will also be multiplied by 2. After glucose is converted to pyruvate:- » If air is absent –Anaerobic Glycolysis NADH (produced at reaction V) reduces pyruvate to lactate. ...
Moreover, blood vessel occlusion has been reported to initiate a hypoxia/necrosis cycle influencing the dynamical balance between glioma cell migration and proliferation. In fact, several clinical and experimental observations suggest that vaso-occlusion could readily explain the rapid peripheral expansion ...
re walking or jogging on the treadmill. Pyruvate would follow the aerobic (in the presence of oxygen) path and enter the Krebs cycle to be broken down into ATP. Think of ATP as the actual gasoline that we burn to make things move. The exhaust from this process is the CO2 we exhale. ...
by predators.Ecologists studying hare populations have found that the North American snow shoe hare follows a roughly ten-year cycle.Its numbers fall tenfold to thirty in a typical cycle, and a hundredfold change can occur.Two factors appear to be generating the cycle: food plants and predators...
It lives in thesame body as our genes, but has a different life cycle and thus re-sponds somewhat differently to evolutionaryforces. In our species,culture and genes are obligate mutualists – an individual cannot evensurvive without tolerably good genes and tolerably good culture. Wehope that ...
seeks not to collate these studies, but to provide a perspective on the fundamental question of whether it is really feasible that so many regulators play important roles and if so, what does this tell us about EMT and more generally, the genetic machinery that controls complex biological ...
