Regulation of metabolism can take place in different compartments in the cell, e.g. in a eukaryotic cell. Compartmentalisation helps to organise diverse or opposing metabolic pathways to take place e.g. mitochondria, in the matrix the TCA cycle takes place and in the inner membrane of the mitochondria the electron transport chain pathway occurs (Bryant Miles, 2003).

Etymology and early use. The phrase quod erat demonstrandum is a translation into Latin from the Greek á½ÏÎµÏ á¼Î´ÎµÎ¹ Î´Îµá¿Î¾Î±Î¹ (hoper edei deixai; abbreviated as Î¿ÎµÎ´). Translating from the Latin into English yields, what was to be demonstrated; however, translating the Greek phrase á½ÏÎµÏ á¼Î´ÎµÎ¹ Î´Îµá¿Î¾Î±Î¹ produces a slightly different meaning.
