Question

Quizplus · Accepted Answer

Ethanol inhibits ADH, which normally promotes reabsorption of water in the kidneys. Without ADH, more water is excreted, leading to increased urine output and potentially dehydration. Therefore, a person consuming a mixed drink would excrete more water than usual due to the inhibition of ADH by the ethanol.
