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).
Lacerum or lacer from Latin may refer to: In anatomy and medicine: 1  Foramen lacerum, a triangular hole in the base of the skull.  Lacerum segment, a part of the course of the internal carotid artery.
According to the fourth declension the plural genitive of virus in Latin is viruum and therefore an Index of Viruses is in Latin an Index Viruum. Virorum is the plural genitive of the Latin noun vir (second declension) meaning man or husband. Consequently an Index Virorum would indicate a list of husbands or men.o what we have here is something of a mixed or invariant declension. Trying to find a plural for something that didn't take a plural (possibly because it was not a count but a mass noun), or at least, one for which no plural is classically attested, is a fruitless endeavour. Best to stick with English and use viruses.
