Presentation Transcript

    1. Biochemistry of respiration

    2. Raw materials Any organic molecule Carbohydrate Lipid Protein

    3. They contain too much chemical energy

    4. So, respiration involves breaking down large complex organic molecules to produce a molecule that contains a small amount of energy

    5. ATP ATP is an immediate source of energy because:- Only one step is necessary to release the energy The amount of energy released is small enough to be useful.

    6. Aim of respiration Synthesis of ATP

    7. Carbohydrate is the major substrate for respiration Soluble carbohydrates exist so they can easily be transported Insoluble carbohydrates exist so they can be easily stored

    8. Overview Four stages:- 1. Glycolysis

    9. 2. Link reaction

    10. 3. Krebs cycle

    11. 4. Hydrogen / electron carrier system

    12. GLYCOLYSIS Occurs in cytoplasm Starts with Glucose 6 carbon compound

    13. GLYCOLYSIS Ends with Pyruvate 3 carbon compound
