cell transport
Storyboard Text
- hey Mary my dearest friend from high school .
- hey is thismaritza?
- I remember passive transport and how it moves from low to high? and did not use energy (ATP) right?
- no passive moved from high to low concentration. Honestly speaking cell transportation was my favorite topic .
- you still remember the bio term ?
- Facilitated diffusion is the transport of substances across biological membere from an area higher concentration to an area lower contraction with the helpnof a transport molecule.
- Well I guess that all we rememeber right..
- I remember this one. its the diffusion or movement of water molecules through a memebrane.
- I once read that osmosis main function is stabilizing the internal environment of organism as it helps keeping water levels blalanced.
- We also osmosis as another type of passive transport types.
- So all these passive transportation types moves from high to low why n to low to high? Wait concentration gradient is a differencd of concentration between two regions and must exist for molecules to flow
- I mean its not that hard to forget osmosis it involves water and only water.
- molecules are said to naturally flow down their concentration levels and concentration level.......
- well I hope learn something from this
- yess that all I remember from bio class
