Question

Cytochrome c can be reduced directly by small molecules such as ascorbate (vitamin c). if ascorbate is added to an oxygenated solution containing purified cytochrome c and cytochrome oxidase, what would you predict would occur?
a.atp synthesis would occur.

Answer 1

I think what would occur is that Oxygen would be reduced to water.  Cytochrome c is a large water soluble transmembrane protein complex found in bacteria and the mitochondrion of eukaryotes. It is a key player in the ATP synthesis in the mitochondria. In the electron transport it transfers electrons between complex II and complex IV.
