Macromolecules of Life
| Term | Definition |
|---|---|
| ActivationEnergy | Amount of energy needed to initiate a chemical reaction |
| ActiveSite | Specific location on an enzyme where a substrate binds |
| AminoAcid | Small compounds made of CHNOS |
| Carbohydrate | Compound composed of only CHO |
| Catalyst | Suubstance which lowers the activation energy of a chemical reaction |
| ChemicalReaction | Process or rearranging atoms and molecules into different substances |
| Enzyme | Special protein that speeds up chemical reactions in biological processes |
| Lipid | Molecules made mostly of CH, store lots of energy |
| Macromolecule | Large molecules that are formed by joining smaller molecules |
| Molecule | Compound in which atoms are held together by chemical bonds |
| NucleicAcid | Complex macromolecules that store and transmit genetic information; CHNOPS |
| Nucleotide | Repeating subunits of nucleic acids |
| Polymer | Molecules made from repeating smaller units |
| Product | Substances present at the end of a chemical reaction |
| Protein | Compound made from amino acids, involved in every function of a living organism |
| Reactant | Substances present at the start of a chemical reaction |
| Substrate | Reactant(s) that bind with an enzyme |
| Monomer | Basic unit of a larger molecule that appears repeatedly |
| Endothermic Reaction | A chemical reaction that absorbs energy |
| Exothermic Reaction | A chemical reaction that releases energy |
| Element | Substance made from a single type of atom |
| Disaccharide | a molecule consisting of two sugars |
| Monosaccharide | a molecule of sugar with C:H:O in a 1:2:1 ratio |
| Polysaccharide | long chain of sugars, examples include: starch, glycogen and cellulose |
| Photosynthesis | process where solar energy is used to convert carbon dioxide and water into glucose and oxygen |
| Cellular Respiration | process where sugar is burned by oxygen to make ATP and releases carbon dioxide and water as byproducts |
