997515916 | How do enzymes catalyze reactions? | by lowering the activation energy required for the reaction to occur | 0 | |
997515917 | True or False: Enzymes start chemical reactions. | FALSE. Enzymes don't start reactions- they SPEED UP reactions that would occur eventually. | 1 | |
997515918 | Enzyme substrate | The reactant that an enzyme acts on | 2 | |
997515919 | The enzyme binds to its substrate, forming what? | Enzyme-substrate complex | 3 | |
997515920 | What is the active site? | The active site is the region on the enzyme where the substrate binds. | 4 | |
997515921 | True or false: Enzymes fit with any shape of molecules. | FALSE. Each substrate/reactant has a unique shape. The have a specific substrate the work on | 5 | |
997515929 | An enzyme's activity can be affected by what three factors? | Temperature, pH and Concentration of the Substrate | 6 | |
997515931 | Each enzyme has an optimal _________ and _________ in which it can function. | Temperature / pH | 7 | |
997515932 | Some enzymes reside in specific organelles, such as... | Enzymes for cellular respiration are located in mitochondria | 8 | |
997515933 | The names of enzymes mostly end in | " ASE" Protease Exception: Pepsin | 9 | |

997515935 | Lactase works on what substrate? | Lactose in the human small intestine | 11 | |
997515936 | Pepsin works on what substrate? | Protein in the human stomach | 12 | |
997515937 | Catalse works on what substrate? | Blood and human cells creating H2O2 Hydrogen Peroxide | 13 | |
997515938 | Lysomsomes | Contain enzymes that digest waste and damaged organelles so the cell can dispose of them | 14 | |
997515939 | Activation Energy | The energy required to initiate a reaction. | 15 | |
997515941 | Optimal Enzyme Temperature Graph | The temperature at which each enzyme specifically works at. In this graph it is 37 degrees C or 98.6 degrees F. | 16 | |
997515942 | Denature (verb) | destroy the characteristic properties of (a protein or other biological macromolecule) by heat, acidity, or other effects that disrupt its molecular conformation. | 17 | |
997515944 | Lock and Key Model | Enzymes are specific. The only wok on the substrate that they "fit." Just like a lock has a specific key to open it. | 18 |
