27. Why do the kidney’s activities require large amounts of energy?
(A) Filtration requires high blood pressure. ->雖然血壓有就會擠過腎絲球，但本身不耗能。
(B) Tubular reabsorption involves active transport. -> 腎臟主要能量都用在把物質拉回來這件事情上。補充：急性腎損傷恢復時有多尿期
(C) Water is removed from the urine by active transport. -> Aquaporin，水通道蛋白不需要ATP
(D) Osmosis occurs in energized proteins in the walls of capillaries. 　-> 不太確定解釋，等後繼大佬解釋
(E) All of the above.
