Decides what goes in and out of the cell. It's the "bouncer". - CORRECT ANSWER -
What is the function of the cell membrane?
active transport - CORRECT ANSWER - Energy-requiring process that moves material
across a cell membrane against the concentration gradient
passive transport - CORRECT ANSWER - Requires NO energy, Movement of molecules
from high to low concentration, Moves with the concentration gradient
facilitated diffusion - CORRECT ANSWER - Movement of specific molecules across cell
membranes through protein channels
Diffusion - CORRECT ANSWER - Movement of molecules from an area of higher
concentration to an area of lower concentration. "When Coach Bell farts, who smells it first?
Who smells it last?"
Osmosis - CORRECT ANSWER - Diffusion of WATER through a semi-permeable
membrane
Homeostasis - CORRECT ANSWER - A tendency to maintain a balanced or constant
