Peripheral Protiens - are attached to either the inner or outer membrane surface, depending on their functions, Integral Proteins - are embedded in the membrane. Some are channels that allow Ions, water, and small water-soluble substance into or out of cell, Gated Channels - opens or close to regulate the passage material , Diffusion - molecules move from a high concertation to a lower concetration , Osmosis - Water molecules; passive no energy required , Active Processes - carrier protein that can move specific substance across the plasma membrane, Exchange Pump - carrier protein move solute in one direction and another solute in the opposite direction, Endocytosis - Packaging of extracellular material into vesicle for importation of cell, Pinocytosis - Vesicles form at the plasma membrane and bring extracellular fluid and small molecules into the cell. This process is often called "cell drinking", Phangocytosis - Vesicles form at the plasma membrane to bring solid particles into the cell. This process is often called "cell eating", Receptor-mediated endocytosis - Targets molecules bind to specific receptor proteins on the membrane surface, triggering vesicles formation, Facilitated diffusion - Uses passive carrier proteins, No energy input with down concentration gradient  , Uniport Carriers - Transports 1 substance, Symport Carrier - transports 2 substance same direction, Antiport Carrier - Transports 2 substance opposite direction, Active transport - Uses carrier proteins, Energy input require and is against concentration gradient, ECF has a net - positive charge, ICF has a net - negative charge, Na+ - Sodium ion, Cl- - chlorine ion, K+ - Potassium ion , A- - Ethanol ion, Hypertonic solution - Solute concentration outside the cell is higher compared to inside the cell (cell shrivels), Isotonic solution - Water concentration inside and outside stay the same due to solute being the same ( cell is balanced) , Hypotonic solution - There is a lower concetration of solute outside the cell compared to inside the cell (cells swell), Solute - Dissolved substance , Intercellular are known to contain - Potassium, Extracellular are know to contain - Sodium ,
