Presentation Transcript

  1. Chapter 9-1: ATP

  2. ATP • Adenosine Triphosphate • Our energy molecule • We store mass amounts in our cells

  3. Cell Energy cont… • To access energy, break the bond that holds the molecule together

  4. Chapter 9-2: Photosynthesis

  5. Photosynthesis • Process plants use • Trap sunlight to make food (glucose) • Food stored as ATP

  6. Photosynthesis cont… • Equation for photosynthesis: 6H2O + 6CO2 ----------> C6H12O6+ 6O2

  7. Photosynthesis cont… • 2 parts to photosynthesis • Light-Dependent Reactions • Happens when sun is out • Take sunlight and make ATP

  8. Photosynthesis cont… • Light Independent Reactions • Happens when sun is down • Take ATP and make glucose

  9. Chloroplast • This is where photosynthesis occurs • Chlorophyll—most common pigment in plants • Makes plants green • Pigments absorb all colors except the one you see

  10. Careers in Biology • Biochemist • Study how organisms grow and develop • PhD required • Could cure disease or create a new “super” plant in the lab • BIG money if you find the cure for a disease! Plus you would save lives!!!
