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