This is the movement from a HIGH concentration to a LOW concentration.
HIGH à LOW
Simple Diffusion:
- Passing through the cell membrane into or out of the cell
- No energy needed
- Passing through the cell membrane into or out of the cell
- No energy needed
Facilitated Diffusion:
- Diffusion through protein channels
- Channels move SPECIFIC molecules across the cell membrane
- No energy needed
- Diffusion through protein channels
- Channels move SPECIFIC molecules across the cell membrane
- No energy needed
Osmosis:
- The movement of WATER across the cell membrane
- The movement of WATER across the cell membrane
Active Transport:
- Diffusion AGAINST concentration gradient
- Diffusion AGAINST concentration gradient
LOW à HIGH
- Uses an protein pump (like a protein channel) that moves
it across the cell membrane
- Needs energy (ATP)
- Needs energy (ATP)
wow.good. with the pictures and those moving things i get more about it:)(sunny)
ReplyDeleteI like your moving pictures! From Rachel and Jessica
ReplyDeleteThe animated pictures make your blog entry stand out compared to others. I plan on using your entry as our review Monday. Great job.
