Question

question 15 (1 point)
which methods of transporting materials across a membrane do not require energy in the form of atp? choose any of the forms of membrane transport that apply. (note: select all options that apply)
active transport
facilitated diffusion
pinocytosis
exocytosis
phagocytosis
osmosis
simple diffusion

Explanation:

• Active transport: Requires ATP as it moves substances against the concentration gradient.
• Facilitated diffusion: Does not require ATP. It uses transport proteins to move substances down the concentration gradient.
• Pinocytosis: Is a form of endocytosis (cellular “drinking”) and requires ATP.
• Exocytosis: Involves the expulsion of substances from the cell and requires ATP.
• Phagocytosis: Is a form of endocytosis (cellular “eating”) and requires ATP.
• Osmosis: Is the diffusion of water across a semi - permeable membrane down the concentration gradient and does not require ATP.
• Simple diffusion: Moves substances down the concentration gradient and does not require ATP.

Answer:

B. facilitated diffusion, F. osmosis, G. simple diffusion
