Passive Transport (VCE SSCE Biology): Flashcards

Movement across membrane without energy, down concentration gradient

Difference in solute concentration between two adjacent areas

Movement of molecules from high to low concentration

Small AND nonpolar (e.g. O₂, CO₂, H₂)

Passive transport using protein channels or carrier proteins

Passive transport of water through semipermeable membrane

Higher solute concentration compared to another solution

Lower solute concentration compared to another solution

From low to high solute (hypotonic to hypertonic)

Becomes turgid (swollen and firm)
