Definition of homeostasis
A condition of equilibrium in the bodys internal environment
A cell membrane…
- covers the cell’s cytoplasm, controls what moves in and out of the cell, connects to other cells and allows body cells to ‘recongize’ each other
explain passive transport
substances move across the cell membrane due to kinetic energy, no ATP is required, they down their concentration gradient via simple diffusion, osmosis, facilitated diffusion and filtration.
Explain active transport
substances move across the cell membrane using ATP, they move against their concentration gradient via active transport and transport in vesicles.
What do Ion channels allow
allow ions to move into or out of the cell
function of a carrier
selectively move substances through the membrane
