Question

1. what are the 3 types of passive transport and provide some details of each

Explanation:

• Simple diffusion: Molecules move from high to low concentration through the lipid bilayer. Examples: oxygen (\(O_2\)) and carbon dioxide (\(CO_2\)).
• Facilitated diffusion: Molecules use transport proteins (channel or carrier) to move down the concentration gradient. Example: glucose transport via carrier proteins.
• Osmosis: Movement of water molecules across a semi - permeable membrane from an area of lower solute concentration to higher solute concentration.

Answer:

The three types of passive transport are simple diffusion, facilitated diffusion, and osmosis.
