7466936319Selectively Permeablea property of cell membranes that allows some substances to pass through, while others cannot0
7466936320Phospholipid Bilayerdouble layer of phospholipids that makes up plasma and organelle membranes1
7466936321Integral Proteinspenetrate the hydrophobic core and often span the membrane (transmembrane)2
7466936323Glycoproteinsproteins that have carbohydrates covalently bonded to them3
7466936324Glycolipidslipid that have carbohydrates covalently bonded to them4
7466936325Passive Transporttransport that does not require the cell to expend energy (high to low concentration)5
7466936326Active Transportenergy-requiring process where a substance moves against the concentration gradient (low to high concentration)6
7466936327Diffusionnet movement of a substance down a concentration gradient (high to low)7
7466936328Facilitated Diffusiondiffusion of solutes across a membrane, with the help of transport proteins8
7466936329Osmosisdiffusion of water across a selectively permeable membrane9
7466936330Hypertonicsolute concentration is greater than inside the cell, cell loses water; plant cells plasmolyze, animal cells crenate10
7466936331Hypotonicsolute concentrations in less than inside the cell, cell gains water; animal cells lyse, plant cells have ideal turgor pressure11
7466936332Isotonicsolute concentrations are the same on both sides of the membrane, cell does not gain or lose water; ideal condition for animal cells12
7466936333Sodium-Potassium Pumpactively pumps Na+ ions out and K+ ions in, 3 Na leave for every 2 K that enter13
7466936336Exocytosisexporting macromolecules by fusion of vesicles with the plasma membrane14
7466936337Endocytosisimporting macromolecules by forming vesicles derived from plasma membrane15
7466936338Phagocytosispart of the cell membrane engulfs large particles or entire cells (cell eating)16
7466936339Pinocytosispart of the cell membrane engulfs small dissolved substances or fluid droplets in vesicles (cell drinking)17
7466936343Fluid Mosaic Modelstates that the membrane is a fluid structure with a mosaic of various proteins embedded in it18
7466936344Transport Proteinsallow passage of hydrophilic substances across the membrane19
7466936345Concentration Gradienta difference in concentration across a distance20
7466936348Aquaporinsfacilitates the passage of water into a cell21
7466936351cholesterolA large, ring shaped lipid found in cell membranes. Its presence helps to maintain flexibility and fluidity in the membrane.22
