Chapter 9 Cellular Respiration Review
  1. Living organisms require to perform cellular work.
     
     
     
     
  2. Energy flows into most ecosystems as and leaves as .
     
     
     
     
  3. Electron transfer drives the transformation of energy and occurs through reactions.
     
     
     
     
  4. Molecules such as NAD+ and FAD act as electron in redox reactions.
     
     
     
     
  5. In cellular respiration, redox reactions occur in a series of steps called the transport chain to form .
     
     
     
     
  6. Cellular respiration comprises three metabolic stages: , acid cycle, and phosphorylation.
     
     
     
     
    • occurs in the to produce two molecules of from the metabolism of one molecule.
       
       
       
       
    • The is converted to CoA, which enters the acid cycle.
       
       
       
       
    • During phosphorylation, NADH and FADH2 donate to the ETC to produce even more ATP.
