How does the accumulation of protons in the intermembrane space contribute to ATP synthesis?
it creates a steep electrochemical gradient across the inner membrane
it releases energy as heat
it transfers electrons between carrier molecules
it combines protons with oxygen to form water
|
What is the role of ATP synthase in oxidative phosphorylation?
to actively transport protons across the inner mitochondrial membrane
to catalyse the synthesis of ATP from ADP and inorganic phosphate
to transfer electrons between carrier molecules
to combine electrons and protons with oxygen to form water
|
During oxidative phosphorylation, protons diffuse back from the intermembrane space into the mitochondrial matrix through , releasing energy and catalysing the synthesis of ATP.
|
