Membrane Transport Flashcards
Active vs passive transport
Active - requires energy
Passive -doesn’t require energy
List 4 types of passive transport
Diffusion
Facilitated diffusion
Osmosis
Filtration
List 3 types of active transport
Primary
Secondary (co-transport)
Endo/exocytosis
Define isotonic
A solution with the same osmotic pressure as body fluids
Define hypotonic
A solution with with lower osmotic pressure (WP) than bodily fluids is hypotonic
Define hypertonic
A solution with higher osmotic pressure (WP) than bodily fluids
Define Endocytosis
The process of actively transporting molecules into the cell by engulfing it with its membrane.
Define exocytosis
the transport of material out of a cell by means of a sac or vesicle that first engulfs the material and then is extruded through an opening in the cell membrane
Define Phagocytosis
the ingestion of bacteria or other material by phagocytes
Chemical buffering systems of the body may include
Bicarbonatea
3 roles of calcium
Blood clotting
Muscle contraction
Neural conduction
