What is its effect on the rate of hydrolysis of ATP to ADP and phosphate ion?If oxygen is no longer available to make ATP, what happens to the transport of Na+?
- How many ATP are produced in oxidative phosphorylation?Cells can generate as many as 36 to 38 molecules of adenosine triphosphate (ATP) from the metabolism of one molecule of glucose. Which cellular process results in this amount of ATP production?A proton gradient is produced by the electron transport chain. Which compartment in the mitochondria contains the high concentration of protons?
- In primary/direct active transport, does ATP always have to be involved? Definitions seem to say the movement must be coupled with an exergonic reaction. Wouldn't the movement of a solute down its concentration gradient be exergonic, or is this an incorrect statement?How does Na+/K+ ATPase/Pump promote osmosis across plasma membrane? How does it establish the basal metabolic rate? Lastly, what does it mean when the pump self-phosphorylates during transportation?Why are oxygen molecules important in oxidative phosphorylation? What are the consequences if they are absent for a short period of time in tissues that routinely use oxidative phosphorylation to produce useful energy?
