Concentration Gradient Flashcards
1
Q
What is a concentration gradient
A
A concentration gradient occurs when the concentration of particles is higher in one area than another
2
Q
What is passive transport
A
When particles diffuse down the concentration gradient, from an area of higher concentration to an area of lower concentration
3
Q
What is active transport
A
When particles move up the concentration gradient from an area of lower concentration to an area of higher concentration
