mixture | a combination of substances |
organic compound | always contain carbon and hydrogen and usually are associated with living things |
enzyme | regulate nearly all chemical reactions in cells |
inorganic compound | made from elements other than carbon |
passive transport | the movement of substances through the cell membrane without the input of energy |
diffusion | random movement of molecules from an area where there is relatively more of them |
equililbrium | where diffusion stops |
osmosis | the diffusion of water through a cell membrane |
active transport | input of energy is required to move materials through the cell membrane |
endocytosis | taking substances into a cell by surrounding with the cell membrane |
exocytosis | contents of a vesicle can be released by a cell |
metabolism | the total of all chemical reactions in an organism |
photosynthesis | producers use light energy to make sugars which can be used as food |
respiration | chemical reactions occur that break down food into simpler substances and release their stored food |
fermentation | to release some of the energy stored in glucose molecules |
