Question

cell transport, homeostasis, feedback quiz 2025
ch statement to active or passive transport
requires atp
particles move from high concentration to an area of low concentration
includes endocytosis and exocytosis
particles move from an area of low concentration to an area of high concentration
includes facilitated diffusion
does not require cellular energy/
moves material against their concentration gradient

Explanation:

To solve this, we recall the definitions of active and passive transport:

• Active Transport: Requires ATP (energy), moves particles from low to high concentration (against gradient), includes endocytosis/exocytosis.
• Passive Transport: Does not require energy, moves particles from high to low concentration (with gradient), includes facilitated diffusion, simple diffusion, osmosis.

Matching Each Statement:

1. Requires ATP → Active Transport (needs energy from ATP).
2. Particles move from high to low concentration → Passive Transport (follows concentration gradient).
3. Includes endocytosis and exocytosis → Active Transport (these processes use energy).
4. Particles move from low to high concentration → Active Transport (against gradient, needs energy).
5. Includes facilitated diffusion → Passive Transport (facilitated diffusion is a passive process).
6. Does not require cellular energy → Passive Transport (defining feature of passive transport).
7. Moves material against their concentration gradient → Active Transport (against gradient requires energy).

Answer:

• Requires ATP: Active Transport
• Particles move from high to low concentration: Passive Transport
• Includes endocytosis and exocytosis: Active Transport
• Particles move from low to high concentration: Active Transport
• Includes facilitated diffusion: Passive Transport
• Does not require cellular energy: Passive Transport
• Moves material against their concentration gradient: Active Transport
