Take a look at the Bozeman Science, Cellular Respiration video, https://youtu.be/Gh2P5CmCC0M?list=PL7A750281106CD067 this is a good way to start our summary of the cellular respiration process. 

Summary of Cellular Respiration:

• Uses energy in glucose to make ATP
• In glycolysis, glucose is split into two molecules of pyruvate, and 2 ATP are produced
• The Krebs cycle and electron transport occur in the mitochondria.
• During the Krebs cycle pyruvate undergoes reactions that produce 2 more ATP and several molecules of NADH and FADH₂
• During electron transport several ATP are made using energy from NADH and FADH₂. 
• Up to 38 molecules of ATP can be produced from one molecule of glucose.
