Presentation Transcript

  1. ATP-ADP Cycle

  2. But first….. Heterotrophs Autotrophs Can NOT make own food… they get their energy by the foods they eat • Make their own food • with light – phototrophs • with chemicals -- chemotrophs

  3. ATP Adenosine triphosphate JOB--- store & release energy + P P P ribose - adenine

  4. ADP Adenosine diphosphate JOB--- energy can be stored by adding another Phosphate.. and becoming ATP + P P ribose - adenine

  5. Releasing energy Releasing energy Storing energy Storing energy ATP ADP + + P P P P P ribose ribose - - adenine adenine

  6. phosphate removed ATP-ADP Cycle • ATP – ADP Cycle

  7. Transformation of Energy • Energyis the ability to do work. • Thermodynamicsis the study of the flow and transformation of energy in the universe. Laws of Thermodynamics • First law-Energy can be converted from one form to another, but it cannot be created nor destroyed. • Second law-Energy cannot be converted without the loss of usable energy. HEAT

  8. Carbohydrates • most commonly broken down to make ATP. • not stored in large amounts • up to 36 ATP from one glucose molecule • Lipids • store the most energy. • 80% of energy in your body • About 146 ATP from a triglyceride • Proteins • least likely to be broken down to make ATP. • amino acids not usually needed for energy • about the same amount of energy as a carb.

  9. ATP-ADP Cycle

  10. Using Biochemical Energy 1) Movement in cell 2) Protein synthesis 3) Active Transport (Low to high concentration across membrane)
