Biochemistry Vocabulary 1. Solution: Generally, a mixture of a liquid and a dissolved solid or gas. 2. Solvent: The larger part of the solution; the part that does the dissolving. 3. Solute: The smaller part of the solution; the part that gets dissolved 4. Saturation: The maximum concentration of a solution. Saturation depends on temperature, volume, and type of solvent 5. Concentration: A measurement of what currently dissolved in a solution, expressed in g/100cm3. Equation in (M÷V) x 100. 6. Solubility: A term meaning the saturated concentration of a solution 7. Precipitate: A dissolved substance that comes out of a solution due to either a change in temperature or volume 8. Metabolism: is the set of life-sustaining chemical transformations within the cells of living organisms. These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their structures, and respond to their environments. 9. Cellular respiration: is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. 10. Chemical reaction: In a chemical reaction, the reactants are changed into the products, which are different substances 11. Reactant: The elements and molecules that go into a chemical reaction 12. Product: The elements or molecules produced from a chemical reaction 13. Yield: to make or produce. 14. Synthesis: The resulting product of a chemical where a new compound is formed from the combination of the reactants 15. Decomposition: The resulting product of a chemical reaction when one or more of the reactants are broken down into simpler molecules or elements. A new substance is also formed. 16. Protein: are large biological molecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within living organisms, including catalyzing metabolic reactions, replicating DNA, responding to stimuli, and transporting molecules from one location to another. 17. Carbohydrate: is a biological molecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen:oxygen atom ratio of 2:1 (as in water); in other words, a C1H2O1 ratio. 18. Lipid (fat): Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides,triglycerides, phospho lipids, and others. The main biological functions of lipids include storing energy, signaling, and acting as structural components of cell membranes 19. ATP: Adenosine triphosphate. The coenzyme used as an energy carrier in the cells of all known organisms; the process in which energy is moved throughout the cell. 20. Anaerobic: cellular respiration in the absence of oxygen, using lipids instead of glucose. 21. Ionic bond: a chemical bond between a metal and a non-metal atom where the electron is transferred from the metal to the non-metal. 22. Covalent Bond: A chemical bond between two non-metal atoms where pairs of electrons are shared between the non-metal atoms. 23. Glucose: A simple sugar or starch; the main source of energy for the body. C6H12O6 is the formula 24. Enzyme: are macromolecular biological catalysts. Enzymes accelerate, or catalyze, chemical reactions.
