bio cell transport

active transport

uses energy and goes against the concentration gradient

passive transport

no energy and follows the concentration gradient

hypotonic

the process of water going into a cell to make the cell swell

hypertonic

the process of water leaving a cell to make the cell shrink

isotonic

the process of the water mass staying the same while the molecules move in and out in an equillibrium

endocytosis

the process of proteins being brought in from energy (active transport)

exocytosis

the process of proteins being taken out by energy (active transport)

water, glucose, protein

components of life smallest to biggest that are transported through cell membranes

glucose

a sugar that is transported through the membrane through facilitated diffusion (passive)

carbon dioxide and oxygen

gases that transport across the membrane through simple diffusion

protein

a molecule that passes through the membrane by endo and exocytosis (active) bc they are too big

ions

charged molecules that transport through the membrane by facilitated diffusion or pumps

simple diffusion

gases, small nonpolar, no energy, passive, high to low concentration

facilitated diffusion

big molecules, glucose, passive, high to low concentration, no energy

osmosis

water only, passive, high to low conc., no energy

endo and exocytosis

uses energy, active, low to high concentration, proteins

pumps

active, low to high concentration, charged molecules
