The KEGG and NCBI databases contain a wealth of information obtained from sequencing and analyzing the complete genome of Acinetobacter baumannii 1656-2, which is a medically important oxidase-negative (cytochrome c oxidaseâ€“negative) bacterium that is multidrug resistant. For this microorganism, which statement regarding oxidative phosphorylation is correct? B- The formation of ATP depends directly on the oxidation of cytochrome c. C- D- Solution Answer- B It is true that the formation of ATP depends directly on the oxidation of cytochrome c. cytochrome c consumes oxygen and synthesis of ATP occour . Cytochrome c oxidase is responsible for reduction of molecular oxygen to water using reducing equivalents donated by cytochrome c. Hence option C is incorrect. .
