Term
| compare and contrast active transport and facilitated diffusion |
|
Definition
| active transport requires energy to move molecules from lower concentration to higher concentration- also called sodium,potassium pump- uses transport proteins, facilitated difusion does not require energy to move molecules across memrane from higher concentration to lower concentration also uses transport proteins |
