Transport Phenomena Crossword Puzzle

QUESTIONS LIST:

• sodium pump: works against the concentration gradient transporting sodium ions out and potassium ions into the cell
• pinocytosis: the way that the plasma membrane “pinches in” to permit a molecule to enter that is too large to diffuse through
• solvent: substance doing the dissolving (water)
• hypertonic: a solution that causes a cell to shrink due to osmosis (water leaves the cell)
• active transport: the movement of substances from high to low concentration that requires atp(energy)
• endocytosis: the movement of of substance into a cell by a vesicle
• phagocytosis: the way an ameba or white blood cell engulf a particle
• osmosis: the movement of water from higher to lower concentration
• passive transport: movement of substances through a membrane from a region of high to a region of low concentration…no atp(energy) needed
• solute: the substance being dissolved (salt)
• diffusion: movement from an area of higher concentration to an area of lower concentration (molecular vibration)
• isotonic: a solution that causes no change in cell size,,,no movement of water
• hypotonic: a solution that causes a cell to swell (water enters the cell)
