    Chat mod needs to be on hand to close thread exactly on 2013
    Might be possible to schedule it automatically as a thread edit :holmes:

    Glycolysis

    ATP hydrolysed Pi combines with glucose making -glucose6phosphate


    Glucose6phospahte

    by isomrase enzyme becomes. fructose 6phospahte another ATP molecule is hydrolysed phosphate molecule attaches to C1 molecule and becomes fructose-1,6-bisphosphate
    They energy released from the hydrolysed ATP activates the hexose 1,6 bisphosphate molecule not to leave the cell

    The hexose 1,6 bisphosphate is broken down into 2 molecules of triose phosphate a 3 C compound

    TP is dehydrogenated by enzymes dehydrogenase and H atoms combine with NAD substrate phosphorylation of ADP and Pi

    Four enzyme catalysed reactions convert TP into 2 molecules of pyruvate

    Substrate level phosphorylation occurs
    Net gain of 2 molecules of ATP formed 4 made but used to kick start the process
    And 2 reduced NAD


    Link reaction

    Pyruvate dehydrogenated and decarboxylated h atoms combine with NAD ,reduced NAD
    Carboxyl group eventually becomes co2

    CoA accepts acetate and carries to kreb cycle

    Kreb cycle

    CoA releases a state and acetate combines with oxcoloacetate to form
    Citric acid (6C)

    6C decarboxylated and dehydrogenated co2 And reduced NAD formed 5c molecule formed

    5c molecule dehydrogenated and decarboxylated
    4c formed changed into another 4c and ATP is phosphorylated

    4c changed into another 4c molecule and dehydrogenated FAD is reduced

    4c into third 4c and dehydrogenated to regenerate oxcoloacetate


    Cycle turns 2 times for each glucose molecule

    Chemosmosis and oxidative phosphorylation

    Flow of protons to generate ATP chemiosmosis

    Reduced NAD and FAD lose H atom and split into H+ and e-

    The e- are carried across the etc and release energy as the pass across etc this provides energy for the H+ to flow thought the electron carries and they accumulate and cause and proton gradient

    The protons diffuse across the inter membrane space and diffuse into the ATP synthase which drives the rotation part and join ADP and pi

    4 Electrons are passed from the last last etc and combine with 4H+ and combine with the final electron acceptor O2 and this produces 2 molecules of water.

    2 H atoms from FAD and 2H atoms from NAD

    Mitochondria adaptation

    Inner membrane folded into cristea for greater S.A for greater respiration

    Many ATP synathase in inner membrane to form ATP for oxidative phosphorylation

    Matrix has many enzymes and reactants for kreb cycle

    Maximum ATP not produce


    Some hydrogens leaked thought mitochondrial membrane not enough protons for proton motive force

    Some ATP used to actively transport pyruvate into cytoplasm

    Some ATP actively transport reduced NAD from glycolysis stage into mitochondria

    Anaerobic respiration
    Mammals
    Pyruvate combines with hydrogen from the oxidised NAD -lactate produced
    Enzyme lactate dehydrogenase used called lactase pathway
    Oxidised NAD back to glucose to pick hydrogen glucolysis can continue.

    Yeast

    Pyruvate converted to ethanal from decarboxylation co2 provided

    Ethanal combines with hydrogen from reduced NAD to form ethanol and alcohol dehydrogenase catalase reaction

    Oxidised NAD back to glucose to pick hydrogen glucolysis can continue.

    Respiratory substrate organic substance for respiration

    The higher the numbers of hydrogen atoms the higher the relative energy value
    More h atoms
    More NAD reduced
    NAD used in etc

    Lipids highest
    Proteins
    Carbohydrates lowest
