Is oxygen a passive transport or an active transport?

Answer 1

They move via passive transport. They move by diffusion. It's only active transport if A) the cell is too big or not fatty enough to move through the membrane and needs help or B) is making the molecules move unnaturally (low to high). Osmosis is also passive transport, but only is used when referring to the movement of water.

Answer 2

Active transport. To go "upstream" requires ATP, a form of energy, to pump against the ion gradient.

Answer 3

well oxygen isn't a transport system it is something that can be diffused across the membranes of cells.

Answer 4

You could call it passive transport, but the correct term is diffusion. Osmosis where water is involved.

Answer 5

Passive (diffusion - along pressure gradient).

Answer 6

Passive transport moves molecules from a high to low concentration gradient.

Answer 7

Oxygen is typically transported into cells passively through diffusion. This process does not require the use of energy.

Answer 8

Passive Transport-Diffusion

Answer 9

active transport.
