Presentation Transcript

  1. Cellular Energy

  2. Cellular Energy • The breakdown of nutrient molecules (food we eat) allows cells to store energy in the form of ATP. • ATP (adenosine triphosphate) is the energy of life.

  3. Cellular Energy • Photosynthesis and cell respiration are complementary processes for cycling carbon dioxide and oxygen. • The reactions are opposites of each other. The products produced from one reaction are the reactants needed to fuel the other.

  4. 3 ways to make energy: • PHOTOSYNTHESIS- Plant cells and many microorganisms use solar energy to combine molecules of carbon dioxide (CO2 ) and water (H2O) into food (glucose C6H12O6) and release oxygen (O2) into the environment. • Occurs in chloroplast

  5. 3 ways to make energy:PHOTOSYNTHESIS sunlight Carbon dioxide + Water Glucose + Oxygen 6CO2 + 6H2O C6H12O6 + 6O2 chlorophyll sunlight chlorophyll

  6. 3 ways to make energy:PHOTOSYNTHESIS • The sun is the key to all life.

  7. 3 ways to make energy:PHOTOSYNTHESIS

  8. 3 ways to make energy: 2.RESPIRATION- OCCURS IN THE MITOCHONDRIA During cell respiration, eukaryotic cells “burn” glucose molecules with oxygen, which produces energy (ATP), carbon dioxide, and water. This process requires OXYGEN. It is aerobic.

  9. 3 ways to make energy:RESPIRATION Glucose + Oxygen Carbon dioxide + Water + ATP C6H12O6 + 6O2 6CO2 + 6H2O + ATP

  10. 3 ways to make energy: 3. Fermentation-(anaerobic respiration) OCCURS IN THE CYTOPLASM glucose is broken down without oxygen into carbon dioxide, ATP, and alcohol Produces less energy than aerobic.

  11. 3 ways to make energy:GLYCOLYSIS • Yeast and other unicellular organisms use this process

  12. 3 ways to make energy:GLYCOLYSIS • When your muscles run out of oxygen they will use this process to make energy. Your muscles produce lactic acid instead of alcohol.
