    Metabolism-All of the chemical reactions in a cell.
    Catabolism-The chemical reactions in the cell that break complex molecules down
    Anabolism-The chemical reaction in the cell that build complex molecules

    Complexity
    Thousands of interrelated compounds, reactions, and enzymes
    All under detailed feedback and control
    Ultimately governed by the DNA and the cell's responses to the environment

    BASIC STRUCTURE OF A MITOCHONDRION

    See attached Figure "Mitochondrion". A schematic representation of a mitochondrion. The breakdown of food molecules leads to a transfer of electrons between enzymes of the respiratory pathway (green). These enzymes pump protons across the inner membrane, building up a proton gradient. The protons then flow through special channels in ATP synthase (orange) resulting in the generation of ATP from ADP and Pi.

    OVERVIEW OF PROCESS OF ATP GENERATION

    Multiple "food" molecules get converted into a small number of common C2 and C4 molecules
    These C2/C4 molecules enter the center of the mitochondria where they are "processed" by the citric acid pathway
    The citric acid pathway gives H+ and e- which are used to generate NADH and FADH2
    These are e-, H+, and energy carrier molecules
    These are used by ...
