Biology Flashcards

5043385427	Plasma Membrane (cell membrane)	Flexible, selectively permeable (having pores or openings) boundary that helps control what enters and leave the cell.	0
5043416101	Lipid Bilayer	double-layered sheet that forms the core of nearly all cell membranes	1
5043424626	Phospholipid	Plasma membrane layers composed of phospholipid molecules arranged with polar heads facing the out side and non polheads facing the inside	2
5043431967	Transport Protien	Protein that moves substances or wastes through the plasma membrane.	3
5043436687	Carbohydrate	organic compound containing carbon, hydrogen, and oxygen in a ratio of one oxygen and two hydrogen atoms for each carbon atom.	4
5043446664	Carbohydrate Chain	substance on the plasma membrane helps identify chemical signals from outside the cell?	5
5043452179	Cholesterol	Blocking system of the cell membrane . (sticks to the polar heads)	6
5043457889	Anchor Protein	helps maintain cell shape	7
5043466487	Receptor Protein	Helps with Identification of cells. (receive messages)	8
5043474234	Osmosis	Diffusion (flow)of water through a membrane	9
5043487577	Diffusion	Movement of molecules from high to low concentration	10
5043505010	Facilitated Diffusion	Passive transport of ion and small molecules across the plasma membrane by transport proteins.	11
5043536813	Active transport	minimum amount of energy needed for reactions to form products in a chemical reaction.	12
