In the course of a hypothetical meal, the stomach expands from 0.25 liters to 1.25 liters. If we assume that no buffering occurs and no acid is produced from the stomach contents, how much acid must be secreted to maintain pH = 1.0? How many grams of ATP would be consumed in the production of that acid?
Why do the kidneys attempt to reclaim the glucose for the body instead of spilling it into the urine?
Ammonia, NH3, and ammonium ion, NH4+, are both soluble in water and could be easily excreted in the urine. Why does the body convert them to urea rather than excreting them directly?
