Glycolysis

• Glycolysis occurs in the cytosol.
• Glycolysis produces small amounts of ATP.
• Glycolysis is used in fermentation and respiration.
• Glycolysis converts glucose (6C) to 2 pyruvates (3C+phosphate)
• Glycolysis uses 2 ATP to break down glucose. (oxidize)
• Glycolysis produces 4 ATP and 2 NADH.
• The NET production of Glycolysis is 2 ATP and 2 NADH.
• NAD+ to NADH is Reduction.
• NAD+ is an electron carrier
• The NADH produced in Glycolysis leads to the Electron Transport Chain.
• The 2 Pyruvic Acids produced at the end of Glycolysis moves to the Krebs Cycle.
• Glycolysis is a fast process.
• Glycolysis alone DOES NOT require oxygen.
• Glycolysis evolved before the other stages of Cellular Respiration and before oxygen was added into the atmosphere.
• You have to invest energy to get energy.
• Two phosphate groups join carbon (makes it less stable) from using energy ATP -> ADP.
• Each half of carbon has a high energy phosphate group and donates high energy electrons and a proton. It is donated to Electron Carriers (NAD+).
• NAD+ -> NADH (Reduction)
• NADH carries an additional proton and two high energy electron carriers.
• 2ADP connects with 2 phosphates and creates 2 ATP molecules.
• 2 molecules of water are produced.
• 2 more ADP take the remaining 2 phosphate groups and creates 2 more ATP molecules.
• Glucose is broken down into two molecules of pyruvate acid.
• Glycolysis results in 4 ATP and 2 NADH.
• Glycolysis has a NET production of 2 ATP and 2 NADH.
