Question

order these transport methods from smallest to largest molecules they can move across membranes. (2 points) simple diffusion for small non - polar molecules; active transport for specific ions and molecules; facilitated or helped diffusion through protein channels for polar molecules; osmosis just for water molecules; vesicle transport for large proteins and sugars

Explanation:

Osmosis transports water (smallest molecules). Simple diffusion moves small non-polar molecules (e.g., O₂, CO₂). Facilitated diffusion handles larger polar molecules (e.g., glucose). Active transport moves specific ions and larger molecules. Vesicle transport carries large macromolecules (proteins, sugars).

Answer:

Osmosis just for water molecules, Simple diffusion for small non-polar molecules, Facilitated or helped diffusion through protein channels for polar molecules, Active transport for specific ions and molecules, Vesicle transport for large proteins and sugars
