Question

What type of transport is occuring here? Look closely for several key indicators!

A. Regular passive diffusion

B. Facilitated diffusion

C. Active transport

Answer 1

B. Facilitated diffusion

Step-by-step explanation:

There are three main types of passive transport: Simple diffusion – movement of small or lipophilic molecules (e.g. O2, CO2, etc.) Osmosis – movement of water molecules (dependent on solute concentrations) Facilitated diffusion – movement of large or charged molecules via membrane proteins (e.g. ions, sucrose, etc.)
