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).

An erratum or corrigendum (plurals: errata, corrigenda) (comes from Latin: errata corrige) is a correction of a published text. An erratum is most commonly issued shortly after its original text is published. Patches to security issues in a computer program are also sometimes called errata. As a general rule, publishers issue an erratum for a production error (i.e., an error introduced during the publishing process) and a corrigendum for an author's error.
