(8 points) Following hypovolemic shock, [a] cells on the afferent arteriole sense a reduction in pressure and release the enzyme [b]. This molecule cleaves a short peptide out of the inactive [c] to make the active [d], which is then converted to [e] by an enzyme in the lungs called [f]. The final molecule will [g] blood pressure by causing the contraction of arterial [h] muscle.

(10 points) Gastric pits, which are part of the stomach [a] (layer), contain specialized cells called [b] cells that secrete protons from their apical membranes. These ions originate when the enzyme [c] converts [d] and [e] into [f] and [g]. Movement of this ion across the apical membrane requires a(n) [h]ase that exchanges a [i] ion from the extracellular space for a [j] ion in the cytoplasm.
