Glycolysis

Cards (25)

  • 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.
