WebMembrane-bound ATP synthases (F0F1-ATPases) of bacteria serve two important physiological functions. The enzyme catalyzes the synthesis of ATP from ADP and inorganic phosphate utilizing the energy of an electrochemical ion gradient. On the other hand, under conditions of low driving force, ATP synthases function as ATPases, thereby generating … WebThe plasma membrane Ca 2+ ATPase (PMCA) is a transport protein in the plasma membrane of cells and functions to remove calcium (Ca 2+) from the cell.PMCA function is vital for regulating the amount of Ca 2+ within all eukaryotic cells. There is a very large transmembrane electrochemical gradient of Ca 2+ driving the entry of the ion into cells, …
