Passive Transport
- movement of substances in a cell membrane without using the cell" s energy
- Oxegen Molecule
- Osmoisis is passive transport, movment of
water molecules only in membrane
- Facilitated diffusion
- Happens when a molecule is to large to pass through a cell membrane
- Uses carrier proteins
- Active transport
- Active transport uses the cells energy
- Diffusion is happens when both sides of membrane are unequal
- goes from area of higher concentration to lower concentration
- depends on the amount of substance on each side
- Equalibrium
