- osmosis and active transport
- osmosis
- water potential is the likelihood of water molecules to diffuse out of or into a solution
- pure water has the highest water potential
- factors that affect rate
- water potential gradient
- the higher the gradient the faster osmosis
- thickness of exchange surface
- the thinner the faster
- surface area of exchange surface
- the larger the SA the faster
- water potential gradient
- water potential is the likelihood of water molecules to diffuse out of or into a solution
- active transport
- against concentration gradient
- uses carrier and channel proteins
- needs energy
- ATP
- undergoes hydrolysis to release energy
- ATP
