2. Indicate whether each of the following statements about the mitochondrial electron tranafer chain and oxidative phosphorylation is true or false F() NADH dehydrogenase complex, cytochrome bej complex, and eytochrome oxdidase are transmem- brane proteins. )Synthesized ATP must be transported into the intermembrane space before it can enter the cytosol (e) Cytochrome c and the P subunit of ATPase are peripheral membrane proteins ?(d) Complexes I, ll, lll, and ? all are proton pumps. (e) Ubiquinone is a hydrophilic molecule. o Uhiquinone and the F, subunit of ATP synthase are peripheral membrane proteine das Tho final eloctron acceptor is H.O.

Explanation / Answer

A- False because cytochrome oxidase here is a mobile carrier located outside the membrane and not in transmembrane space.

B-True

C-True

D-True

E- False because it is lipid soluble and soluble in the hydrophobic region in the membrane.

F-False because it is transmembrane and not peripheral protein.

G- False ...the final electron acceptor is the oxygen and not H2O
