4. Which of the following statements best describes theoval-shaped arrows involving UQ and UQH2, which are located withinthe membrane in the colorful KEGG diagram?
The quinone pool remains tightly bound to the membrane surface,where UQ serves as a substrate for Complexes I and II
The quinone pool is loosely bound within the membrane, where UQserves as the substrate for Complexes I and II
The quinone pool is loosely bound within the membrane, where UQserves as the substrate for Complex III
The quinone pool is loosely bound within the membrane where UQH2serves as the substrate for Complexes I and II
5. The KEGG and NCBI databases contain a wealth of informationobtained from sequencing and analyzing the complete genome ofAcinetobacter baumannii 1656-2, which is a medicallyimportant oxidase negative (cytochrome c oxidase- negative)bacterium that is multidrug resistant. For this microorganism,which statement regarding oxidative phosphorylation is correct?
This microbe possesses subunits of cytochrome c oxidase andtherefore displays cytochrome c oxidase activity
The formation of ATP depends directly on the oxidation ofcytochrome c.
The cytochrome bd complex allows oxygen to be reduced by thequinone pool
Subunit a of the F-type ATPase has 876 amino acids
