What is oxidative phosphorylation?
Oxidative
phosphorylation is a process in which electrons are transferred from
electron donors to oxygen, which acts as
electron acceptor. The oxidation-reduction reactions are involved in
the formation of proton gradient. The main role in oxidative
phosphorylation is played by the enzyme ATP synthase (complex V).
This enzyme complex consists of F0
and F1
components. The F1
headpiece is a peripheral membrane protein complex and contains the
site for ATP synthesis from ADP and inorganic phosphate. F0
component is a part of membrane protein complex, which acts as a
channel for crossing of the protons from inner mitochondrial membrane
to the mitochondrial matrix. For every two protons passing through
F0–F1
complex, synthesis of one ATP molecule takes place.
