Question

1. facilitated diffusion is an example of ____ transport.

○ osmotic
○ active
○ passive
○ carrier

Explanation:

Facilitated diffusion is a type of passive transport. In passive transport, substances move across the cell membrane from an area of higher concentration to an area of lower concentration without the use of energy. Facilitated diffusion uses transport proteins (channels or carriers) to help move substances (such as polar molecules or ions) across the membrane, but it still occurs down the concentration gradient and does not require energy input like active transport does. Osmotic refers specifically to the movement of water. Carrier is more about the type of protein involved rather than the overall transport type.

Answer:

C. passive
