Select the best answer or answers from the choices given: Which is reabsorbed by the proximal convoluted tubule cells? (a) Na+, (b) K+, (c) amino acids, (d) all of the above.
Expert Solution
Step 1
The proximal convoluted tubule is a part of the kidney's nephron, and it is the primary site where most of the reabsorption occurs.
Step 2
The reabsorption of 65% of sodium-potassium, water and chloride occur within the proximal convoluted tubule. The proximal convoluted tubule reabsorbs 100% of amino acids and glucose and 90% of bicarbonate.
Hence the correct option is d
