Presentation Transcript

  1. Photosynthesis and Cellular Respiration • Cellular processes Cornell Notes #8

  2. What is Cellular Respiration? • Transforms unusable energy from food molecules into usable energy for the cell • Produces ATP • Uses oxygen • Occurs in mitochondria

  3. CR inside mitochondria Glucose + Oxygen Carbon dioxide + Energy

  4. What cells use cellular respiration? • Most cells

  5. What is Fermentation? • Process to produce energy (ATP) without the use of oxygen. • Two types • Lactic acid fermentation - produces lactic acid and carbon dioxide • Alcohol fermentation - produces ethanol

  6. Fermentation Alcohol fermentation Lactic acid fermentation

  7. What is Photosynthesis? • Using the sun’s energy to make food • Requires a pigment called chlorophyll • Occurs inside chloroplasts

  8. Photosynthesis Carbon dioxide + Water Glucose + Oxygen

  9. What cells use Photosynthesis? • Plant cells

  10. Ticket out the door: Summary • In your own words, summarize todays lesson. Use complete sentences (3-5)
