Bio1100 Chapter 5 Chap 4   Energy   Chap 6
  1. Energy exists in two states: potential   energy and kinetic   energy.

     
  2. Living systems transfer energy in chemical   reactions that involve energy change.

     
  3. An important molecule in the transformation of energy in organisms is ATP   (adenosine triphosphate).



     
  4. Energy flows   from the sun to living organisms.

     
  5. Some plant cells contain chloroplasts with pigments for photosynthesis: producing sugars   with energy from sunlight  .













     
  6. Cellular respiration requires oxygen   to produce ATP   from glucose  .



     
  7. In anaerobic   conditions, glycolysis   is followed by fermentation.

     
  8. Other macromolecules such as proteins   and fats   can also enter cellular respiration via different pathways.
