Q
Transport
A
cellular activities require ions (Na, Cl, K), gases (CO2, O2), proteins, amino acids, removal of excess water & waste
Active = energy required
- cytosis: exocytosis, endocytosis (phagocytosis, pinocytosis)
- active transport = carrier proteins (Na-K pump, H+ pump, cotransport
Passive = energy not required
- diffusion
- osmosis
- facilitated diffusion
