Membrane Flashcards
Hypotonic
When too much water enters the cell and it explodes
Carrier proteins
Proteins embedded in the phospholipids that take in chemicals
Hypertonic
Water leaves the cell and the cell withers
Isotonic
Equal amounts of water in the cell and environment
Osmosis
Diffusion of water across membrane
Sodium-potassium pump
A carrier protein that takes out sodium and takes in potassium
Endocytosis
Food is taken into the cell
Exocytosis
Wastes are taken out of the cell
Equilibrium
Internal balance condition
Ion channels
Controls what kind of ions go thru and which ones don’t
Phagocytosis
Cell eating
Phagocyte
Is what eats the cell
Contractile vacuole
Absorbs water for the cell
Active transport
Low water potential to high water potential
Passive transport
Moves high water potential to low
Concentration gradient
Changes the solutes in an area
Vesicles
Pouches that take the food in the cell
Turgor pressure
Pushes membrane to cell wall
Diffusion
Disperses the solutes to where it’s equal
Facilitated diffusion
Transport process
