| Question | Answer |
|---|---|
| acid | Substance that can release a hydrogen ion when dissolved in water |
| adenosine triphosphate (ATP) | Energy-storing compound found in all cells. |
| alkali | Substance that can accept a hydrogen ion (H+); substance that releases a hydroxide ion (OH−) when dissolved in water; a base. |
| amino acids | Building block of protein. |
| anabolism | Metabolic building of simple substances into materials needed by the body. |
| anion | Negatively charged particle (ion). |
| aqueous solution | Pertaining to water; an aqueous solution is one in which water is the solvent. |
| atomic number | The number of protons in the nucleus of an element’s atoms; a number characteristic of each element. |
| atoms | Smallest subunit of a chemical element. |
| base | The broad, superior portion of the heart. A lower portion or foundation. Substance that can accept a hydrogen ion (H+); substance that releases a hydroxide ion (OH−) when dissolved in water; an alkali. |
| buffer | Substance that prevents sharp changes in a solution’s pH. |
| carbohydrates | Simple sugar or compound made from simple sugars linked together, such as starch or glycogen. |
| carbon | Element that is the basis of organic chemistry. |
| catabolism | Metabolic breakdown of substances into simpler components; includes the digestion of food and the oxidation of nutrient molecules for energy |
| catalysts | Substance that speeds the rate of a chemical reaction. |
| cation | Positively charged particle (ion). |
| chemistry | Study of the composition and properties of matter. |
| cholesterol | Lipid synthesized by the liver that is found in all plasma membranes, bile, myelin, steroid hormones, and elsewhere; circulates in the blood and is stored in liver and adipose tissue; implicated in the development of atherosclerosis. |
| colloids | Mixture in which suspended particles do not dissolve but remain distributed in the solvent because of their small size (e.g., cytoplasm); colloidal suspension. |
| compound | Substance composed of two or more chemical elements. |
| covalent bond | Chemical bond formed by the sharing of electrons between atoms. |
| denaturation | Change in structure of a protein, such as an enzyme, so that it can no longer function. |
| disaccharide | Compound formed of two simple sugars linked together, such as sucrose and lactose. |
| electroencephalograph | Instrument used to study the brain’s electric activity; record made is an electroencephalogram. |
| electrolytes | Compound that separates into ions in solution; substance that conducts an electric current in solution. |
| electron | Negatively charged particle located in an energy level outside an atom’s nucleus. |
| elements | One of the substances from which all matter is made; substance that cannot be decomposed into a simpler substance. |
| equilibrium | Sense of balance. |
| glucose | Simple sugar; main energy source for the cells; dextrose. |
| glycogen | Compound built from glucose molecules that is stored for energy in the liver and muscles. |
| hydrophilic | Mixing with or dissolving in water, such as salts; literally “water loving.” |
| hydrophobic | Repelling and not dissolving in water, such as fats; literally “water fearing.” |
| ion | Atom or molecule with an electrical charge; anion or cation. |
| ionic bond | Chemical bond formed by the exchange of electrons between atoms. |
| isotope | Form of an element that has the same atomic number as another form of that element but a different atomic weight; isotopes differ in their numbers of neutrons. |
| kinetic energy | The energy of movement, such as the energy of molecular vibrations. |
| metabolism | All the physical and chemical processes by which an organism is maintained. |
| mixture | Blend of two or more substances. |
| molecule | Particle formed by covalent bonding of two or more atoms; smallest subunit of a compound. |
| monosaccharide | Simple sugar; basic unit of carbohydrates. |
| neutron | Noncharged particle in an atom’s nucleus. |
| nitrogen | Chemical element found in all proteins. |
| nucleotides | Building block of DNA and RNA; one is also a component of ATP. |
| pH | Symbol indicating hydrogen ion (H+) concentration; lower numbers indicate a higher H+ concentration and higher acidity. |
| pH scale | System for indicating the relative concentration of hydrogen and hydrozide ions in a solution. The scale ranges from 1 to 14, with 1 most acidic and 14 most alkaline (basic) and 7 as neutral. |
| phospholipid | Complex lipid containing phosphorus; major component of the plasma membrane. |
| polysaccharides | Compound formed from many simple sugars linked together (e.g., starch, glycogen). |
| potential energy | Stored energy, such as gravitational energy, the energy of position in a gravitational field. |
| proteins | Organic compound made of amino acids; found as structural materials and metabolically active compounds, such as enzymes, some hormones, pigments, antibodies, and others. |
| protons | Positively charged particle in an atom’s nucleus. |
| radioactive | Pertaining to isotopes that fall apart easily, giving off radiation. |
| radiotracer | Radioactive substance administered internally for purpose of diagnosis. |
| solute | Substance that is dissolved in another substance (the solvent). |
| solution | Homogeneous mixture of one substance dissolved in another; the components in a mixture are evenly distributed and cannot be distinguished from each other. |
| solvent | Substance in which another substance (the solute) is dissolved |
| steroid | Category of lipids that includes the hormones of the sex glands and the adrenal cortex. |
| substrate | Substance on which an enzyme works |
| suspension | Heterogeneous mixture that will separate unless shaken. |
| triglycerides | Simple fat composed of glycerol and three fatty acids. |
