Question

question 15 (1 point)
which of the following processess requires energy to occur?
diffusion
osmosis
facilitated diffusion
exocytosis

Explanation:

• Diffusion: Passive transport (no energy), movement of particles from high to low concentration.
• Osmosis: Passive transport (no energy), movement of water across a semipermeable membrane from low to high solute concentration.
• Facilitated diffusion: Passive transport (no energy), uses transport proteins for movement from high to low concentration.
• Exocytosis: Active transport, requires energy (ATP) to move large molecules out of the cell (e.g., secretion of proteins).

Answer:

D. exocytosis
