Fermentation |
Fermentation is a metabolic process that converts sugar to acids, gases, or alcohol. |
|
|
Fermentation does not require what? |
Oxygen |
|
|
Bacteria catabolizes glucose using a process known as ________ |
Fermentation |
|
|
What is the purpose of ATP? |
To get ATP |
|
|
What is the purpose of carbohydrate fermentation? |
determine the ability of an organism to ferment different sugar with or without the production of gas |
|
|
What color does the medium turn if the bacteria are able to break down the carbohydrates? (Fermented) |
Medium will turn yellow |
|
|
What color does the medium turn if the bacteria are not able to break down the carbohydrates? (No fermentation) |
Medium will remain red |
|
|
Carbohydrates media tubes used |
Maltose Glucose sucrose mannitol lactose dextrose |
|
|
Name the tube that allows us to detect production of gas by the bacteria. |
Durham Tube |
|
|
What is Phenol red |
is the ph indicator. that tells us whether a bacteria ferments carbohydrates. (Used to detect production of acids) |
|
|
Catabolism |
Break molecule. Release energy |
|
|
Anabolism |
Build a molecule. energy is consumed |
|
|
What color does a medium generally turn if the pH is lowered (becomes acidic)? |
Turns yellow with gas bubble |
|
|
In carbohydrate fermentation we do not use the _____ _______ ______ |
Electron transport system |
|
|
What are the electron carriers |
NAD+ FAD They pick up electrons |
|
|
What are the products of cellular respiration? |
ATP CO2 carbon dioxide H2O water |
|
|
When testing for carbohydrate fermentation what was the outcome for E. aerogenes? |
all of them produced acid and gas |
|
|
When testing for carbohydrate fermentation what was the outcome for E.coli? |
- acid and gas was NOT produced for sucrose -So sucrose was the only one that did not produce acid and gas. |
|
|
What is the purpose of fermentation? |
regenerate NAD+ Thats how it is able to make ATP without oxygen |
