Diffusion, Osmosis, Active Transport Flashcards
1
Q
What is Diffusion?
A
When something goes from high to low concentration.
2
Q
What is Osmosis?
A
Where molecules go from a low concentration to a high concentration, through a semi-permeable membrane.
3
Q
What is Active Transport?
A
Where dissolved molecules go through a cell membrane to get from a low concentration to a high concentration.
4
Q
Does Active Transport go with or against the gradient.
A
Against.
5
Q
How does the molecules have enough energy to go against the gradient? ( active transport)
A
They get energy from respiration.
