Transcript of Cellular Process
Cells have to carry out numerous functions to survive.
These function range from replication and energy conversion to molecule transport and the various signaling used in cellular communication.
Respond to Stimuli
//Diffusion, random movement of particles from greater concentration gradient to lesser concentration which is either liquid or gas.
//Simple Diffusion, small molecules such as oxygen, ethanol, and carbon dioxide, the molecules could easily cross the membrane.
//Facilitated Diffusion, involves protein channels in the flow of substances across the membrane.
//Osmosis, is the movement of water or any solution through the cell membrane.
the concentration of solute is greater.
the concentration of solution is greater and solute is lesser.
equal amount of concentration is found inside the cell.
//Endocytosis, is a process by which the cell engulfs a larger molecule that cannot be passively transported inside the cell.
//Phagocytosis, 'cell-eating' involves the ingestion of large molecules.
//Phinoytosis, 'cell-drinking' ingesting small molecules and/or fluids surrounding the cell.
//Exocytosis, is an internal transport that takes place within cell and carries outside of the plasma membrane.
//Passive Transport, is a process by which small molecules easily pass through the membrane without requiring energy (ATP). They may be facilitated by protein.
//Active Transport, is a process by which larger molecules pass through the membrane requiring energy (ATP).
//SOLUTE, is a substance dissolve in a larger solution found in lesser amount.
//SOLVENT, is a substance dissolve in solution found in large amount.
//SOLUTION, is a liquid mixture of two or more substances in which the molecules of the substances are mixed.
//CONCENTRATION GRADIENT, is the gradual change in the concentration of molecules.
//PERMEABLE MEMBRANE, is a membrane that allows certain substance to pass through.
Allows all substance to pass through.
Allows selected substance to pass through.
Does not allow any substance to pass through.
