cell processe


mixture is a combinationof substances in which individuales substancea retai8n their own properties.
organic compounds always contains carbon and hydrogen and usually as associated with living things.
inorganic compounds are made up from elements other than carbon.
enzymes certain proteins are called enzymes regualate nearly all chemical reactions in cells.
passive transport the movement of stubstaces though the cell membrane without the input of energy.
diffusion this random movement of molecules from an area where there is relativily more of them into a area were there are relativily fewer of them.
equilibrium occurs when moleculs of one substance are spread evenly thoughout another substance.
osmosis a type of passive transport that occurs when water diffuses though a cell membrane.
active transport energy-requiring process in which transport proteins bind in with partical and move them though a cell membrane.
endocytosis process by a cell takes in another substance by surrounding it with the cell membrane.
exocytosis process by which vesicles release their contects outside cell.
metabolism a total of all chemicalreactions in a organism.
photosynthesis process by which plants and many other producers use light energy to produce a simple sugar from carbon dioxide and water give off oxygen.
respiration process by which producers and consumers release stored energy from food molecules.
fermentation process by which oxygen-lacking cells and some one-celled organisms release small amounts of energy from glucose molecules and produce wastes such as alcohol carbon dioxide and lactic acid.
