endocytosis | process by which a cell takes in a substance by surrounding it with the cell membrane |
mixture | a combination of substances that retain their properties when combined (example: tossed salad) |
exocytosis | process by which vesicles release their contents OUTSIDE the cell |
osmosis | the diffusion of water through a cell membrane |
metabolism | the total of all chemical reactions in an organism |
diffusion | type of passive transport in cells in which molecules move from areas where there are more of them to areas where there are fewer of them |
respiration | series of chemical reactions used to release energy stored in food |
enzyme | type of protein that regulates nearly all chemical reactions in a cell |
inorganic compound | compound such as water that is made of other elements other than carbon and hydrogen and whose atoms can be arranged in only one structure |
organic compound | compound that always contains carbon and hydrogen (examples: lipids, carbohydrates, proteins, and nucleic acids) |
active transport | energy-requiring process in which transport proteins bind with particles and move them through the cell membrane |
equilibrium | occurs when molecules of one substance are spread evenly throughout another substance |
photosynthesis | process by which plants use light energy from the sun to make food |
