element Any substance that cannot be broken down into simpler substances (O, N, Na, S, C) compound When 2 or more elements combine chemically (H20, CO2) Carbohydrates An energy-rich organic compound like sugars and starches Lipids An energy-rich organic compound that stores more energy than carbohydrates Proteins Large organic molecules that form parts of cell membranes and help rebuild cell parts Amino acids The building blocks of proteins Enzymes Nucleic acids DNA A type of protein that speeds up chemical reactions Long organic molecules that contain the instructions that cells need to carry out all of the functions of life Genetic material that carries info. about an organism and is passed from parent to offspring RNA Found in the cytoplasm and plays a role in production of proteins Organic compounds Compounds in living things that contain the element carbon The ability of a cell membrane only allow Selectively permeable some substances in and some substances out The main method by which small molecules move across the cell Diffusion membrane from high concentration to low concentration Osmosis The diffusion of water through a selectively permeable membrane Passive transport cell transport methods that do NOT require energy Active transport Engulfing The movement of materials through a cell membrane that requires cellular energy A method of active transport in which the cell membrane forms a vacuole around the needed substance Transport proteins Photosynthesis Large proteins imbedded in the cell membrane that pick up materials and bring them into the cell using energy The process by which a cell captures energy in sunlight and uses it to make food Autotroph An organism that makes its own food Heterotroph An organism that cannot make its own food Pigment Colored chemical compounds that absorb light Chlorophyll The main, green photosynthetic pigment Stomata Small openings underneath leaves that are used for gas exchange Cellular respiration The process by which your cells obtain energy from glucose Fermentation An energy-releasing process that does not require oxygen Alcoholic fermentation Lactic acid fermentation A type of fermentation that occurs in yeast in which alcohol is a by-product A type of fermentation that takes place in your body in times of low oxygen levels
