PBS Unit 3
Unit 3 Vocabulary Words for Principles of Biomedical Sciences
| Word | Definition |
|---|---|
| Hypotonic | A solution which was a lower solute concentration compared to another. |
| Insulin | A protein hormone given out by the pancreas. It is used for the metabolism of carbohydrates and the regulation of glucose levels in the blood. |
| Ionic Bond | A bond created by the attraction of oppositely charged ions. |
| Isotonic | A solution which has the same solute concentration compared to another. |
| Lipid | A compound that is insoluble in water. |
| Macromolecule | A giant molecule formed by joining many smaller molecules. |
| Molecule | A combination of atoms held together by covalent bonds. |
| Monomer | A building block of a polymer. |
| Monosaccharide | Simplest type of sugar - it is only a single sugar molecule. |
| Negative Feedback | A change in one variable which creates a response that goes against that change. |
| Nutrient | Needed by the body to maintain life and health. |
| Nutrition | How an animal takes in and uses food substances. |
| Osmosis | The movement of water across a selectively permeable membrane from an area of higher concentration to an area of lower concentration. |
| pH Scale | A logarithmic scale which tells one how many hydrogen ions there are in a solution. |
| Polarity | Charge differences on opposite ends of a structure. |
| Polymer | A large molecule consisting of many repeating chemical units or molecules linked together. |
| Polysaccharide | A polymer of thousands of simple sugars formed by dehydration synthesis. |
| Positive Feedback | Feedback that tends to magnify a process or increase its output. |
| Protein | A three dimensional polymer made of monomers of amino acids. |
| Solute | A substance that is dissolved in a solution. |
| Solution | A liquid that is a homogeneous mixture of two or more substances. |
| Solvent | The dissolving agent of a solution. Water is the most versatile solvent known. |
| Substrate | A substance acted upon by an enzyme. |
| Atom | The smallest particle of an element that can exist either alone or in combination. |
| Adenosine tri-phosphate (ATP) | A compound composed of adenosine and three phosphate groups that supplies energy for many biochemical cellular processes by undergoing enzymatic hydrolysis. |
| Amino Acid | An organic monomer which serves as a building block of proteins. |
| Calorie | The amount of heat energy required to raise the temperature of 1 g of water by 1°C. |
| Carbohydrate | A sugar in the form of a monosaccharide, disaccharide or polysaccharide. |
| Catalyst | A substance that enables a chemical reaction to proceed under different conditions (as at a lower temperature) than otherwise possible. |
| Chemical Bond | An attractive force that holds together the atoms, ions, or groups of atoms in a molecule or compound. |
| Chemical Indicator | A substance used to show the condition of a solution with respect to the presence of free acid or alkali or some other substance. |
| Chemical Reaction | Chemical transformation or change; the interaction of chemical entities. |
| Compound | A substance consisting of two or more elements in a fixed ratio. |
| Concentration Gradient | An increase or decrease in the density of a chemical substance in an area. Cells often maintain concentration gradients of ions across their membranes. |
| Covalent Bond | A type of strong chemical bond in which two atoms share one or more pairs of valence electrons. |
| Dehydration Synthesis | A chemical reaction in which two molecules are bonded together with the removal of a water molecule. |
| Dietary | The kinds and amounts of food available to or eaten by an individual, group, or population. |
| Disaccharide | A double sugar molecule made of two monosaccharides bonded together through dehydration synthesis. |
| Electrolyte | Any of the ions that in a biological fluid regulate or affect most metabolic processes |
| Element | The smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms. |
| Enzyme | Any of numerous complex proteins that are produced by living cells and catalyze specific biochemical reactions at body temperatures. |
| Feedback | Information obtained from the results of a process that is used in guiding the way that process is done. |
| Glucose | A monomer of carbohydrate, simple sugar. |
| Homeostasis | The maintenance of relatively stable internal physiological conditions (as body temperature or the pH of blood). |
| Hormone | A product of living cells that circulates in blood and produces a specific often stimulatory effect on the activity of cells. |
| Hydrogen Bond | A type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond. |
| Hydrolysis | A chemical process that splits a molecule by adding water. |
| Hydrophilic | Having an affinity for water. |
