6314774911 | hydrolase | hydrolyzes chemical bonds (Atlases, proteases) | 1 | |
6314777422 | Isomerase | rearranges bond within a molecule to form an isomer | 2 | |
6314781498 | Ligase | forms a chemical bond (DNA ligase) | 3 | |
6314783816 | Lyase | break chemical bonds by means other than oxidation or hydrolysis (pyruvate decarboxylase) | 4 | |
6314790537 | Kinase | transfer a phosphate group to a molecule to a molecule from a high energy carrier, such as ATP (phosphofructokinse PFK) | 5 | |
6314797698 | Oxidoreductase | runs reduce reactions | 6 | |
6314801670 | Polymerase | polymerization (addition of nucleotides to the leading strand of DNA by DNA polymerase) | 7 | |
6314804334 | Phosphatase | removes a phosphate group from a molecule | 8 | |
6314817453 | Protease | hydrolyzes peptide bonds | 9 | |
6314842582 | Competitive inhibitors | -compete with substrate for the active site -Vmax is not changed -Km is increased, because you can overcome the inhibitor by increasing the amount of substrate - the affinity is decreased because it takes more substrate to reach Km -Think of it as a alcoholic versus freshman The alcoholic is going to take a lot longer to get drunk because his tolerance is increased (Km increased), thus his receptors are less sensitive, his affinity has decreased A freshman who doesn't drink, will only need a few beers to get drunk (Km) so the Km is decreased, thus the freshman has more affinity for the alcohol from one beer. | ![]() | 10 |
6314895703 | Non competitive inhibitor | -Inhibitor can bind to the enzyme with or without the substrate bond to it -Vmax is decreased because the amount of functional ES complexes is decreased. -the substrate can bind without any problems, so Km does not change | ![]() | 11 |
6315017462 | Uncompetitive inhibition | -Inhibitor binds the to allosteric site of the ES complex and does not allow the product to be made. -Reduces the number of functioning ES complexes, thus reduces product -Vmax is decreased -Km has decreased, the affinity has increased, the enzyme complex has such a high affinity for the substrate that it will not leave the active site of the enzyme complex On the plot,it is opposite of what you say since its the inverse. | ![]() | 12 |
6315255331 | Line weaver-Burke Plot | slope: Km/Vmax y-intercept: 1/vmax x-intercept: -1/Km ** Increase in substrate concentration means a decrease in the value along the x-axis because it is the inverse ** increase the reaction rate V is a decrease in the inverse of the reaction , so reaction rate increases, the value along the y-axis decreases. | ![]() | 13 |
6315306695 | Bronsted-Lowry Acids and bases | BAD Bronsted, Acid, Donates Acid: Protons (H+) donors Base: Proton (H+) accepters | ![]() | 14 |
6315330449 | Oxidation Reaction Reduction Reaction | Oxidation: Gain of oxygen molecule, loss of hydrogen atoms, loss of electrons Reduction: is the opposite of oxidation | 15 | |
6315342432 | Exergonic Endergonic | Negative Delta G Postive Delta G | 16 | |
6315342433 | Ka value pka value | -the larger the Ka the stronger the acid; the smaller the Ka value, the weaker the acid -lower pka, stronger the acid, easily deprotonated -pH greater than pka, acid is deprontonated (basic solution) | 17 | |
6315393392 | Secondary structure | Hydrogen bonds between back bond, Proline kinks for beta sheets, and alpha helix | 18 | |
6315398089 | Tertiary structure | hydrophobic and hydrophilic interactions between amino acids residues located more distantly from each other in the polypeptide chains. | 19 | |
6315410854 | Quaternary structure | various bonds between separate chains | 20 | |
6315575959 | Vmax | Constant, it depends on enzyme concentration and what enzyme you have. Vmax is when all substrates are fully saturated, when enzymes are attached to active site all the time | 21 | |
6315601515 | Km | How much substrate you need to have in order to make 1/2 vmax -measure of the enzymes affinity for that specific substrate -Km low, the enzyme has a high affinity for that substrate -Km high, the enzyme does not have a high affinity for that substrate (drink a lot, need more alcohol to get buzz) | 22 | |

Need Notes?
While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
