Definition
| BREAKDOWN of complex organic molecules for energy production and degradation. |
|
|
Term
|
Definition
| SYNTHESIS of cell constituents from simpler molecules |
|
|
Term
| Purpose of oxidation/reduction reactions: |
|
Definition
| one O/R system my oxidize another O/R system releasing energy. Releasing of a sufficient amount of energy can drive the synthesis of ATP. |
|
|
Term
| True or False: All bacterial pathogens are heterotrophs: |
|
Definition
|
|
Term
| How do heterotrophs derive energy: |
|
Definition
oxidation of organic compounds- carbs, lipids, proteins.
(There is a requirement for preformed organic compounds which are needed to provide energy sources) |
|
|
Term
| Energy production by aerobic respiration: (what system?) |
|
Definition
| Electron transport chain. |
|
|
Term
| Electron transport chain: |
|
Definition
| functions to accept electrons from reduced compounds and transfer them to O2 with the resulting formation of water. |
|
|
Term
| 3 Fundamental biochemical pathways required for oxidation of glucose through aerobic respiration: |
|
Definition
1. glycolysis
2. Kreb's cycle
3. electron transport |
|
|
Term
| What is it called when any organic compound is oxidized completely to carbon dioxide and water: |
|
Definition
|
|
Term
| What do the oxidase test reagents do? |
|
Definition
| oxidase test reagents are artificial electron acceptors- test for aerobic respiration |
|
|
Term
| Testing for the presence of Catalase is for what purpose? |
|
Definition
| To find if the bacteria are aerobic since catalase is a byproduct of aerobic respiration. |
|
|
Term
| Terminal electron acceptors in anaerobic respiration: |
|
Definition
| NO3-, SO4-, CO2. Can test for this with the nitrate reduction test. |
|
|
Term
| Bacteria catabolize proteins as a source of what? |
|
Definition
|
|
Term
| True or False: Mechanisms of energy production in fermentation are anaerobic but do involve a respiratory chain or cytochromes. |
|
Definition
| FALSE: fermentation includes anaerobic mechanisms of energy production, which do not involve a respiratory chain or cytochromes. |
|
|
Term
| True or False: Fermentation commonly leads to incomplete oxidation of carbohydrates. |
|
Definition
|
|
Term
|
Definition
| lactic acid, ethanol, acetic acid, butyric acid, butanol, propionic acid or acetone - used for biochemical identification. |
