The Krebs Cycle and Electron Transport. Glycolysis Review. Glycolysis is the process of taking one molecule of glucose and breaking it down into 2 molecules of pyruvic acid 2 ATP are needed to start the reaction net 2 ATP and 2 NADH are netted Occurs in the cytoplasm

Coenzyme A to form Acetyl-CoA
inter mitochondrial space = between 2 membranes
Electrons are moved to the ETC
The electrons, once at the end of the chain, will attach to hydrogen ions and oxygen atoms to form water
Occurs on the inner membrane of the mitochondria
Once this is used up, muscles get their energy from lactic acid fermentation
