The Steps of Respiration - Coggle Diagram

- - - - phosphate groups added (phosphorylation)
        
        1 ATP used - provides phosphates + energy
    - - oxidation
        
        2 pairs of H atoms removed
        
        to REDUCE NAD
        
        (taken to electron transport chain)
        
        NAD
        Nicotinamide Adenine Dinucleotide
        
        coenzyme
        
        hydrogen (H) carrier
        
        When accepts H - becomes reduced NAD or NADH+ H+
    - - energy released (exothermic)
        creates 4 molecules of ATP (from ADP)
      - enter mitochondria to
        participate in further reactions
- - - - then split into electrons + protons
        (protons released into matrix)
    - - by oxidative
        photophosphorylation
    - - oxidised NAD + FAD regenerated
        
        available to be reduced again in process of aerobic respiration pathway
        
        why important?
        
        enables aerobic respiration to continue
    - - catalysed by enzyme
        cytochrome oxidase
- - - - loss of 1 molecule
        of CO2 per pyruvate
      - oxidation reaction
        hydrogen lost used to reduce NAD
      - produces 2C acetate
    - - coenzyme A is released + free to
        react w/ another pyruvate
      - produces acetylcoenzyme A
- - - - removal of
        CO2 + 2Hs
      - production of 1 ATP
        molecule
    - - oxidative decarboxylation
        removal of:
        
        CO2
        
        2Hs - used to reduce NAD
        (produce 3ATP in ETC)
    - - which will produce
        2ATPs in ETC
