Cell Transport Flashcards
Hypertonic Solution
More solute and less solvent
Hypotonic
More solvent and less solute
Isotonic
Equal solute and solvent
How will hypertonic and hypotonic things move?
hypo to hyper
Diffusion
Movement from high to low
Small, nonpolar molecules move through the phosphlipids
Ex: Oxygen
Facilitated Diffusion
Move from high to low
Small, polar molecules move through the protein channel
Ex: Glucose
Osmosis
Water moves to dilute until equal
Protein Pump
Forces molecules through against the concentration gradient (low to high)
Requires ATP
Ex: Ions
Phagocytosis
Engulfing a large solid particle
Requires ATP
Ex: Bacteria
Pinocytosis
Ingesting liquid into a cell
Requires ATP
Ex: Proteins found in liquid
Exocytosis
Cell vomit
Release of a large molecule from the cell
Ex: Cell waste
