Potassium depletion increases the rate of glycolysis in rena
     Potassium depletion increases the rate of glycolysis in renal cells while decreasing the rate of oxidative phosphorylation in these same cells even under normal (physiological oxygen levels. Answer \"Choice 1\" if Choice 1 is greater than Choice 2, \"Choice 2\" if Choice 2 is greater than Choice 1, or \"No difference\" if Choice 1 Choice 2. Again, your three answer choices are: 1) Choice 1, 2) Choice 2, or 3) No difference.   
  
  Solution
1. Choice 2: Pyruvate kinase activity under low potassium levels is highest quantity.
2. Chioce1 : cytochrome c oxidase activity is higher in normal potassium level
3. Choice 1: concentration of protons in the mitochondrial intermembrane space is highest under normal potassium levels.
4. Chioce1: rate of oxidation by Complex 1 under normal potassium level is higher.
