large molecules that could interfere with Krebs
cycle and oxidative phosphorylation. Pyruvate can
pass freely into the matrix.

Outer membrane A barrier that stops entry of
large molecules that could interfere with Krebs

pass freely into the matrix.
Intermembrane space Activity of electron carriers
in the inner membrane causes a reservoir of H to
build up in the space as a temporary energy store
before being used to make ATP

ATP synthase Molecule that makes ATP from ADP and
P using the energy from electrons obtained from
reduced NAD and FAD. Molecules span the inner
membrane and have channels that allow H ions to
pass through.
