Cellular respiration

  1. 1. Cellular Respiration
  2. 2. Respiration Synthesises large molecules like proteins, DNA & RNA Transports objects within the cell such as chromosomes Pumps molecules & ions across cell membranes using active transport
  3. 3. ATP → ADP + P Adenosine triphosphate Splits into adenosine diphosphate + phosphate, energy is released ATP does not travel through membranes; each cell makes their own is mitochondria
  4. 4. Mitochondria In the mitochondria, organic compounds are broken down by enzymes These are controlled reactions Respiration is the controlled release of energy from organic compounds to form ATP. The organic substances are USUALLY lipids and carbohydrates
  5. 5. Anaerobic Respiration
  6. 6. Anaerobic respiration Without oxygen Glucose is converted into pyruvate; called glycolysis Small amount of energy is produced In humans, pyruvate converted into lactic acid Yeast convert pyruvate into ethanol and carbon dioxide All of these products are toxic!!! No more ATP is produced
  7. 7. Aerobic Respiration
  8. 8. Aerobic Respiration Pyruvate, produced by glycolysis, can be further broken down using OXYGEN Occurs in Mitochondria (eukaryotes) Pyruvate oxidation produces up to 10 X more ATP than just glycolysis Carbon dioxide and water are waste products
