Question

which of the following processes listed below do you think would not require atp? transport of sodium across a cell membrane against its concentration gradient. pumping an antibiotic from inside of the cytoplasm of a bacterial cell to the outside. transporting water across membrane from an area of low solute concentration to an area of high solute concentration.

Explanation:

Transporting water across a membrane from an area of low solute concentration to an area of high solute concentration is osmosis, a passive - transport process that does not require ATP. Transport of sodium ions against the concentration gradient and pumping an antibiotic out of a bacterial cell are active - transport processes that require ATP.

Answer:

Transporting water across membrane from an area of low solute concentration to an area of high solute concentration.
