-Enzymes-
| Question | Answer |
|---|---|
| What are enzymes? | proteins that catalyze chemical reactions. |
| How do enzymes work? | By lowering the activation energy. |
| All of the work being done inside any cell is being done by: | Enzymes. |
| What is Oxidation? | the loss of an electron (or hydrogen). |
| What are Autotrophs? | Organisms that synthesize their own nutrients; include some bacteria that are able to synthesize organic molecules from simpler inorganic compounds. |
| What are Heterotrophs? | Organisms that obtain their nutrition by breaking down organic molecules in foods; include animals and fungi. |
| What is Anabolism? | the total series of chemical reactions involved in synthesis of organic compounds. |
| What is Catabolism? | the series of chemical reactions that breakdown larger molecules. |
| What is Homeostasis? | The ability to maintain a relatively constant internal environment. |
| What is Energy Activation? | The minimum amount of energy required for a given reaction to occur; varies from reaction to reaction. |
| What are Co-enzymes? | Chemicals required by a number of enzymes for proper functioning; also known as enzyme co-factors. |
| What is Reduction? | The gain of an electron or a hydrogen atom. The gain of electrons or hydrogen's in a chemical reaction. |
| What is Glycolysis? | The universal cellular metabolic process in the cell's cytoplasm where 6-carbon glucose is split into two 3-carbon pyruvate molecules, and some ATP and NADH are produced. |
| What is the substrate? | The biological molecule that the enzyme will attack. |
| The enzyme grabs onto the substrate with a special area called: | The active site |
| What is the active site? | A specially shaped area of the enzyme that fits around the substrate. |
| What is the Active site sometimes called? | The keyhole of the lock. |
| What is Catalysis? | When the substrate is changed. |
| What do enzymes do? | Complete very specific jobs and do nothing else. |
| Enzymes are: | Proteins. |
| What binds to the active site of an enzyme? | A substrate. |
| True or false, An enzyme can only bind one reactant at a time. | False. |
| True or false, An enzyme speeds up a chemical reaction in the cell, but can only be used once. | False. |
| What are substrates converted into? | Products. |
| What also catalyzes reactions? | A few RNA molecules called ribozymes. |
