    Theres not much u need to know about wine just that alcohol is produced by the anaerobic respiration of yeast. You could use the yeast Sacchromyces Cerevisiae which is also the yeast used in bread making.

    i know metabollic pathway which is sort of similar

    a set of enzyme catalysed reactions
    may be anabolic (e.g. protein synthesis) or catabolic (e.g. digestion of carbohydrates)

    i think metabolism refers to all the biological reactions that occur in a cell

    Metabolism is a combination of anabolism and catabolism. Anabolism is the making of complex molecules from simple molecules and catabolism is the opposite as the breakdown of the complex molecules.

    I guess metabolism is just the sum total of all the chemical reactions which are occuring in the body.

    ANABOLISM + CATABOLISM = METABOLISM
