BIOL201 Ch7.5 | Metabolism Without Oxygen | OpenStax Biology

Biology 201 Lecture Video Covering Chapter 7.5 of OpenStax Biology Summary:

Aerobic respiration uses oxygen as the terminal electron acceptor 

Anaerobic respiration uses other molecules as a terminal electron acceptor but is less effective 
Molecules like sulfur, sulfate, nitrate can be used  

Fermentation is a process to deal with Pyruvate and NADH from glycolysis. Getting rid of these allows glycolysis to continue. 
Ethyl Alcohol fermentation is a key biotechnology that humans have used to preserve food. Baking bread, making beer / wine 
Lactic acid fermentation also is used to preserve food, human cells can also do this when very low on oxygen 

Aerobic Respiration - Anaerobic Respiration - Fermentation
