Osmosis Flashcards
1
Q
what is Osmosis
A
the movement of water through the cell membrane
2
Q
what does it mean if the ICF is hypertonic,
what direction will osmosis go
A
the ICF has less solution than the ECF so the cell will shrivel up
- ECF to ICF
3
Q
What does it mean if the ICF is isotonic,
what is the direction will osmosis go
A
the cell is at its optimum stage, the ICF and ECF have the same concentration/amount of solution, so no movement of water
4
Q
What does it mean if the ICF is Hypotonic.
What direction with osmosis go
A
the cell is too full and will explode
osmosis will go from ICF to ECF
5
Q
describe what resting membrane potential
A
at rest, the intracellular space has more negative charges than the extracellular space which results in a ‘electrical gradient’
