Structure of the Mitochondria
Mitochondria are the cell organelle where aerobic respiration occurs.
Mitochondria have 2 membranes with the inner membrane (cristae) folded.
Cristae: Folded inner membranes increases surface
area. Electron transport occurs here.
Matrix: Inner compartment of mitochondria. Contains
enzymes for the Krebs Cycle.
Outer Compartment: Space between inner &
outer membranes. Area where H+ concentrates.
The 1st step of respiration, Glycolysis, occurs
just outside the mitochondria in the cytoplasm.
