Describe the structure of a mitochondrion and relate to ATP production. What will be an ideal response?
ANSWER: Mitochondria are enclosed by a double membrane. An outer membrane that surrounds the
organelle itself and an inner membrane that contains numerous folds. There are two spaces
within the organelle. The space between the two membranes is the outer compartment and
the innermost space is surrounded by the internal membrane.
The innermost cavity is where the Krebs cycle reactions occur. During this process, two ATP
molecules are produced and H+ are captured by NAD and FAD. These carries transport the
H+ to the inner membrane where they are pumped into the outer compartment via the
electron transport system. These ions accumulate in the outer compartment and a
concentration gradient is established. As the ions flow down their concentration gradient they
pass through an enzyme that catalyzes the conversion of ADP to ATP.
