Despite their role in oceanic CaCO3production, the physiological processes responsible for calcification in foraminifera are poorly understood Here, the authors show that calcification is driven by rapid transformation of bicarbonate to carbonate inside the cytoplasm, achieved by active outward proton pumping.
