Anaerobic/lactic/Ethanol Flashcards
What process doesn’t make much energy?
Anaerobic processes
What is the most common of Anaerobic processes?
Fermentation reactions
How many different types of reaction are in fermentation and what is used?
20 different types and 2ATP/ glucose
What is the final electron acceptor?
organic molecule cannot be O2 because this is Anaerobic respiration
Muscle cells in the absence of oxygen
Lactic acid fermentation
This process uses 2 pyruvic acids> (one step reaction)= 2 lactic acid> utilizes 2 NADH (from EMP) to convert it to lactic acid?
Lactic Acid Fermentation
In lactic acid fermentation not much energy is produced because?
the 2NADH is being used
An example of Lactic Acid Fermentation?
muscle cells in humans; Streptococcus (facultative anaerobe) can survive in the presence of O2 forever on the 2 ATP
An organism that is aerotolerant; can be used in the presence of O2 but never uses it; lives in the vagina helps maintain pH 3.5-4.5
Lactobacillus
Pyruvic acids> (one step reaction) 2 ethanol molecules
Ethanol fermentation
Ethanol fermentation produces?
CO2 & Ethanol
What molecule is used in Ethanol Fermentation?
2 NADH
Products of ethanol fermentation?
yeast, beer, wine
In all fermentation processes how many ATP are produced?
2 ATP
What is mannitol?
a sugar additive added to agar can differentiate bacteria through their fermentation
