Which of the following is not an effect of aldosterone?

a. Increased excretion of hydrogen ions from the fluid in the kidneys

b. Increased retention of sodium ions from the fluid in the kidneys

c. Increased retention of potassium ions from the fluid in the kidneys

d. Increased retention of water from the fluid in the kidneys

Hey, everyone. Let's take a look at this question together. What is the function of aldosterone in the cells of the renal tubules? Is it? Answer choice. A increase sodium reabsorption. Answer choice b increase potassium absorption. Answer choice C promote water excretion or answer choice D none of the above. Let's work this problem out together to try to figure out which of the following answer choices best explains the function of aldosterone in the cells of the renal tubules. So in order to solve this question, we have to recall what we have learned about aldosterone and its function in the cells of the renal tubules to determine which of the following answer choices is the correct answer. And we can recall that aldosterone acts on the cells of the renal tubules in order to promote the reabsorption of sodium. And the reason for that promotion of the reabsorption of sodium is to help with sodium retention to prevent sodium loss in urine, which is crucial for electrolyte balance and overall fluid homeostasis. So looking at our answer choices, we can identify answer choice a increase sodium reabsorption as the correct answer. Since aldosterone acts on the cells of the renal tubules to increase sodium reabsorption or electrolyte balance and overall fluid homeostasis. And all other answer choices are incorrect since aldosterone does not increase potassium absorption and instead enhances potassium excretion and aldosterone does not promote water excretion and instead promotes water retention. So answer choice A is the only correct answer choice. I hope you found this video to be helpful. Thank you and goodbye.
