粒線體在大部份的教科書裡均會被描繪成為橢圓形狀，然而這與事實是完全的背道而馳。570Please respect copyright.ＰＥＮＡＮＡSmrQjHTqYl
粒線體在細胞內並無固定形態，且經常會改變自身的形狀。570Please respect copyright.ＰＥＮＡＮＡaOA6rDeWmQ

(圖2)圖中的鬼劃符並非是茶餐廳侍應生字體、亦不是醫生字體，而是粒線體的各種倩影。570Please respect copyright.ＰＥＮＡＮＡ0pD3BXX7iJ

由此可見得到粒線體的形象百變，絕非是普通的一個橢圓形這麼簡單。570Please respect copyright.ＰＥＮＡＮＡJ7tk299GAG

另一點值得注意的是圖中的藍色三角型，它標示著粒線體即將一分為二的位置;570Please respect copyright.ＰＥＮＡＮＡp7UsiejZ38
有一些處於中間位置，而有一些則位於界乎邊緣的位置。570Please respect copyright.ＰＥＮＡＮＡ5VKmPHlAXr

(圖3)橙色框架為粒線體在邊緣位置一分為二，而綠色框架為粒線體在中間位置一分為二。570Please respect copyright.ＰＥＮＡＮＡn96huF31jM

兩者的分別究竟是隨機所致，還是別有用心做成的呢?570Please respect copyright.ＰＥＮＡＮＡ2qkrgXydyI

(圖4)經過一系列的研究發現，往中間分裂的粒線體為正常運作的粒線體，以一變二從而更有效率為細胞提供能源。570Please respect copyright.ＰＥＮＡＮＡd95IyFu7TQ

而朝邊緣分裂的粒線體大多是有問題的粒線體，這樣做的目的是提供訊號號令細胞殲滅自己，分解過程涉及名為lysosome的細胞器官，且被稱之為Mitophagy。570Please respect copyright.ＰＥＮＡＮＡJMfVP4CfX4

有不少證據顯示，若過量的粒線體分裂過程處理失當的話，便會引致神經衰退、心臟問題甚至是癌症等疾病，所以絕對不能看少。570Please respect copyright.ＰＥＮＡＮＡpY5Hu53hab
