Cell Transport Flashcards
What Is Active Transport
When it does require ATP to move molecules thru the membrane
What is Passive transport
When it does not require ATP to move molecules thru the membrane
What is a concentration gradient
A difference in the concentration of a substance across a distance
What has to happen for equilibrium to be reached?
When molecules reach a point of equal concentration so they move back and forth across the membrane at a constant rate so the net movement overall is zero.
Passive transport is high to low, or low to high?
High to low
Active transport is high to low, or low to high?
low to high
Hypotonic
Low solute and high water concentration
Hypertonic
High solute and low water concentration
Isotonic
Same amout of water and solute concentration
