Cellular Respiration

What is Cellular Respiration???
It involves various metabolic pathways that break down carbohydrates and other metabolites with the build up of ATP. It consumes oxygen and produces carbon dioxide. Cellular respiration is consist of four phases: Glycolysis, Preparatory reaction, citric acid cycle or Krebs cycle, and Electron Transport Chain. Glycolysis breaks down glucose into two molecules of pyruvate. Preparatory reaction is when the pyruvate enters a mitochondrion and oxidized to a two carbon acetyl group and removes carbon dixoide. The Citric acid cycle occurs in the mitochondrion and produces NADH & FADH, it  gives off carbon dioxide and produces one ATP. The Electron transport chainis where the electron passes from higher to lower energy states and allows energy to be released and stored for ATP production...............pretty cool to me. Cellular Respiration is a very important process for our bodies!
