Question
are the following types of cellular transport passive or active? match them correctly
osmosis
exocytosis
facilitated diffusion
diffusion
endocytosis
molecular (sodium potassium) pump
active transport
passive transport
Brief Explanations
- Passive transport (no energy, down concentration gradient): Osmosis (water diffusion), Facilitated Diffusion (with protein, no energy), Diffusion (molecules spread).
- Active transport (needs energy, against gradient): Exocytosis (vesicle release), Endocytosis (vesicle uptake), Sodium - Potassium Pump (uses ATP).
