Quizplus · Accepted Answer

H⁺ secretion and bicarbonate reabsorption occur simultaneously in the kidney tubules through a process called bicarbonate reabsorption. This process involves the H⁺ ions being secreted into the tubule lumen while bicarbonate ions (HCO₃⁻) are reabsorbed into the bloodstream to maintain acid-base balance.
