  • Welcome to Biology! 
  • Welcome to Biology! 
  • Today you will all be learning about cellular respiration 
  • What is cellular respiration?
  • Cellular respiration is the process that happens in a cell that helps keep a cell alive
  • During Cellular Respiration a glucose molecule is broken down into carbon dioxide and water. This process produces a small amount of ATP but most of the ATP is produced in the oxidative phosphorylation phase.
  • Wait so you're telling me that in cellular respiration electrons also play a big role in the cycle? Because i heard that the electron transport chain helps by carrying NAD+ and FAD+ which become NADH and FADH when they gain electrons.
  • Yes and i am also saying that all this happens in the mitochondria which is in the Cytoplams of the cell. another nig process is the kreb cycle which is when acetyl coa combines with a four carbon molecule and then produces NADH FADH2 and ATP
  • yes you are both correct but youre also forgetting about glycolisis which is when glucose is broken down into molecules of pyruvate. this also creates ATP and NAD+ becomes NADH. this then leads us to the pyruvate oxidation which is when puruvate enters the mitochondrial matrix and CO2 is released and NADH also is produced. 
  • wow i love cellular respiration.
