Abstract: | Paracrystalline arrays of helical configuration were observed in the mitochondrial intracrystal spaces following prolonged ageing of mitochondriain situ. The occurrence of these mitochondria with the paracrystalline arrays, average diameter of about 70 Å, appeared to increase following an increase in the time of ageingin situ.The exact function of the mitochondria containing the paracrystalline arrays is unknown. These mitochondria could not possibly be responsible for the overall decline in the State 3 respiration, respiratory control index and the ADP/O ratio observed with intact mitochondria isolated after prolonged ageingin situ 21]. |
