Which of the following is INCORRECT about Aldosterone;

#Unit 7. System Physiology – Animal
  1. Aldosterone exerts nearly 90 percent of the mineralocorticoid activity of the adrenocortical secretions, but cortisol, the major glucocorticoid secreted by the adrenal cortex.
  2. Aldosterone’s mineralocorticoid activity is about 3000 times greater than that of cortisol, but the plasma concentration of cortisol is nearly 2000 times that of aldosterone.
  3. Aldosterone increases reabsorption of potassium and simultaneously increases secretion of sodium by the renal tubular epithelial cells, especially in the principal cells of the collecting tubule
  4. A high concentration of aldosterone in the plasma can transiently decrease the sodium loss into the urine to as little as a few milliequivalents a day
