Movement of Materials in and Out of Cells (HSC SSCE Biology): Flashcards

Controls which substances can pass through

Net movement from high to low concentration, no energy

Net movement of water from high to low water concentration

Uses carrier/channel proteins, high to low, no energy

Equal solute concentration, no net water movement

Lower solute concentration, water moves into cell

Higher solute concentration, water moves out of cell

Movement from low to high concentration, requires ATP

Cell eating - engulfing solid particles

Higher SA:V ratio allows faster substance movement
