Mitochondrial Structure: Two Types of Subunits on Negatively Stained Mitochondrial Membranes

Donald F. Parsons 1

1 Ontario Cancer Institute, Toronto 5, Canada

Projecting subunits were seen on the cristae of all 11 types of mitochondria examined by electron microscopy. These consisted of a stem, 30 to 35 Å wide and 45 to 50 Å long, and a round head 75 to 80 Å in diameter. The outer membranes of rat liver mitochondria showed regular arrays of hollow cylindrical subunits 60 Å by 60 Å.
