Catalase can produce this molecule from hydrogen peroxide, and the sodium­potassium pump uses this molecule to catalyze the hydrolysis of ATP into ADP.
The NPA motif is responsible for the selectivity of some major intrinsic proteins for this molecule, and the Kok cycle describes how a certain manganese­containing enzyme oxidizes this molecule; that enzyme is photosystem II. Vasopressin enhances the reabsorption of this molecule in the collecting ducts of the (*) kidney. Catalase can produce this molecule from hydrogen peroxide, and the sodium­potassium pump uses this molecule to catalyze the hydrolysis of ATP into ADP. For 10 points, name this molecule that makes up 70% of the total volume of a typical cell, as well as 60% of the human body.
