HBio Org Cmpd #4,5
| Term | Definition |
|---|---|
| Polymer: nucleic acid Monomer: | nucleotides |
| Parts of a nucleotide | 5 Carbon sugar, phosphate group, nitrogen base |
| 2 types of nucleic acids | RNA, DNA |
| Function of DNA | store/transmit hereditary info (proteins) |
| Function of RNA | protein synthesis |
| examples of lipids are | fats, oils, waxes |
| Polymer: proteins Monomer: | amino acids |
| 4 functions of proteins control rate/speed of chemical reaction | |
| Form bones/muscles | |
| Transport stuff in/out of cells | |
| Help fight disease | |
| protein precursor amino acids | |
| Enzyme Liver Lab: Chemical Equation H¬¬¬¬2O2 + Catalase --> O2g + H20 + Catalase | |
| Name of Sugar found in milk (disaccharide) Lactose | |
| Milk Digestion Lab: Chemical Equation Lactose + Lactase --> glucose + galactose + Lactase | |
| milk sugar enzyme name Lactase | |
| the type of chemical reaction Hydrolysis | |
| involved in splitting of lactose | |
| How do enzymes affect chemical reactions? They act as a catalyst by speeding up the chemical reaction rate. | |
| liver enzyme name catalase | |
| Enzyme Lab - Name of substrate hydrogen peroxide | |
| Catalase: optimum pH / optimum temperature pH = 7 temp = 25 - 30° | |
| How many amino acids are there? 20 | |
| peptide bond the bond between two amino acids | |
| poly- many | |
| polypeptide many peptide bonds~protein | |
| catalyst proteins speed up chemical reaction rates | |
| enzyme names end in… -ase | |
| Enzymes are specific. Example: lactase only works with lactose | |
| Are enzyme structures changed | |
| during a chemical reaction? No | |
| Can enzymes be reused? Yes; therefore, we only need them in small amounts | |
| Substrate reactant of an enzyme catalyzed reaction | |
| (what the enzyme works on) | |
| active site the place on the enzyme where the substrate fits | |
| lock and key model enzymes are specific; lactase only works with lactose | |
| 5 factors that affect enzyme function pH, temperature, ion concentration, coenzymes, | |
| concentration (enzyme and substrate) | |
| optimum ideal; the best | |
| denature unravel | |
| coenzyme some enzymes require coenzymes to function |
