The diffusion of particles across the cell membrane through carrier proteins is called this

• osmosis

• facilitated diffusion

• diffusion

• active transport

Sugar molecules cross the membrane in this way

• diffusion

• osmosis

• facilitated diffusion

• active transport

Passive transport does not use
