F-type ATPases in the apical domain of the plasma membrane.

mature through fusion with vesicles from the TGN ultimately into lysosomes.

some cancer cells are highly dependent on glycolysis for ATP production.

proto-eukaryotes were anaerobic and the presence of mitochondria allowed them to be aerobic.

inverting the orientation of the transporter proteins in the membrane.

appears to be important for cancer cells becoming metastatic.

Nothing would change; this is the normal Ran-GAP and Ran-GEF distribution.

continue to pump ions and to hydrolyze ATP, but only generate heat in the process.

have nothing to do with pH and reducing environment.
