Pu010 2. You are studying a bacterial protein, Pmp 7, that pumps one potassium (Kt) ion into the cell for each calcium ion (Ca²+) that is moved out of the cell. Pmp 7 uses energy from light to pump these ions across the membrane. Experiment 1: You make an artificial membrane vesicle that has Pmp7 as the only protein on the membrane. Pmp 7 is orientated on this artificial membrane vesicle as it is oriented in a bacterial cell, and...
