Types of transport:
Passive transport
Active transport
Does not require energy
Requires energy
Goes with a concentration gradient (high
concentrations to low)
Goes against the concentration gradient (low to high)
Examples:
Example:
Diffusion - movement of particles/substance
across a membrane, down a concentration
gradient
Protein pumps- proteins in the membrane that use energy to transport
particles/substance against the concentration gradient
Osmosis - movement of water across a
membrane
Vesicle mediated transport - piece of the cell membrane that is 'breaking off'
or 'joining to' in order to let things in and out of the cell. Typically with large
molecules
***Think of a plant cell lab!
- Exocytosis - outside
***think of hypo, hyper, and isotonic
- Endocytosis - inside
- pinocytosis - drinking
Facilitated diffusion - diffusion using a channel
protein
- phagocytosis - eating
