While traveling through the rain forests of peru, you are introduced to a rare and exotic plant. you discover that it contains a toxin that blocks the reabsorption of sodium ions from the proximal tubule. if administered, what affect would this toxin have on the reabsorption of water and other electrolytes? while traveling through the rain forests of peru, you are introduced to a rare and exotic plant. you discover that it contains a toxin that blocks the reabsorption of sodium ions from the proximal tubule. if administered, what affect would this toxin have on the reabsorption of water and other electrolytes? the toxin would significantly decrease the amount of water reabsorbed but would significantly increase the number of other electrolytes reabsorbed by the proximal tubule. the toxin would significantly increase the amount of water absorbed and the electrical gradient for reabsorbing chloride. the toxin would significantly decrease the amount of water and certain electrolytes reabsorbed by the proximal tubule. the toxin would significantly increase the amount of water and calcium ions reabsorbed by the proximal tubule.
