9.7 Biochemistry: 9. ATP

Answers:

  1. Note the different arrangement of information compared with that for glycolysis and oxidative decarboxylation in the flowchart. Hydrogens at the top react with oxygen from the left to form water at the right. Energy released by this oxidation causes phosphorylation of ADP to ATP.


  2. Flowchart for FADH2

  3. NADH + H+ + 3 ADP + 3 Pi + 1/2O2 → NAD+ + 3 ATP + H2O

    FADH2 + 2 ADP + 2 Pi + 1/2O2 → FAD + 2 ATP + H2O



  		4.  ATP NADH FADH2
    Glycolysis of one glucose 2 2

    2 pyruvic acid &#8594 acetyl CoA
    		2

    2 turns of the TCA cycle 2 6 2
    Oxidative phosphorylation to ATP
    		10 2
    Total ATP from one glucose after completion of oxidative phophorylation = 4 + 30 + 4 = 38 ATP
