Atp production

  1. 1. ATP Production Cellular Respiration:
  2. 2. What is ATP? -stands for Adenosine Triphosphate. -often called the “molecular unit of currency” -a chemical compound which cells use to store energy or to release energy. -consists of the adenine, ribose sugar, and 3 other phosphate groups.
  3. 3. ATP’s main purpose is to transport chemical energy within cells for metabolism. In this production, the Mitochondrion is the production centers of ATP.
  4. 4. NADH and FADH2 • Are electron carriers that are collected during cellular transport • Collects energy that will be turned into ATP during the Electron Transportation Chain.
  5. 5. Stages of ATP Production: • Glycolysis: In glycolysis, glucose (a six carbon sugar) is split into two molecules of a three-carbon sugar. These 2 molecules are call Pyruvate. Glycolysis produces two molecules of ATP and 2 molecules of NADH . In the presence of oxygen, glycolysis is the first stage of Aerobic Cellular Respiration. Without oxygen, it is called Anaerobic Cellular Respiration.
  6. 6. Stages of ATP Production • Conversion: If the 2 Pyruvates have enough oxygen, it becomes 2 acetyl-CoA. During this step, you can generate 2 NADH and CO2. It occurs in Mitochondria.
  7. 7. Stages of ATP Production • Krebs Cycle/Citric Acid Cycle: This stage requires oxygen so it is Aerobic. During this step, the 2 Acetyl-CoA will be broken down. Since it is broken, you can generate 2 FADH2, 6 NADH, 2 ATP and CO2. It occurs in Mitochondria.
  8. 8. Stages of ATP Production • Electron Transport Chain: Electrons that have been produced by the break down of glucose and stored in molecules called electron acceptors are used along with oxygen we breathe in to produce 34 ATP and water.
  9. 9. • Fermentation: If the 2 Pyruvates don’t have enough oxygen, they go to Fermentation. There are 2 types of Fermentation: Alcohol Fermentation and Lactic Acid. Alcohol Fermentation occurs in Yeast and produces Alcohol and CO2. Lactic Acid occurs in Muscles and produces Lactic Acid and Muscle Fatigue. We can only generate 2 ATP in Fermentation.
  10. 10. • The process of cellular respiration produces about 36 ATP molecules that can be used for energy inside of the cells. • In prokaryotic cells, cellular respiration produces 38 ATP molecules while in eukaryotic cells have 36. • Plant and animal cells (eukaryotes) spend 2 ATP in moving products though membranes. Thus, producing only 36 ATP. • In bacterial cells (prokaryotes), they don’t require energy to move products in their simpler cells. Thus, producing 38 ATP.
