Question

Which process will be immediately inhibited if cytochrome c is unable to interact with cytochrome c oxidase?

a. transfer of electrons from cytochrome c to coenzyme Q
b. transfer of electrons to H 2 O H2O
c. transfer of electrons from cytochrome c to O2
d. transfer of electrons from coenzyme Q to cytochrome c

Answer 1

Answer:

the correct answer is C

Explanation:

What cytochrome C does is change electrons to oxygen to reduce it to two water molecules

Answer 2

Answer:

c. transfer of electrons from cytochrome c to O2

Explanation:

Actually in the electron transport chain cytochrome c oxidase is the final enzyme. From each 4 cytochrome c molecule  It receives electron , transfer them dioxygen to form 2 molecules of water. 4 protons are used in order to make 2 water molecules and 4 protons are translocated across the membrane which create electrochemical potential.Hence electrochemical potential is generated and is utilized by ATP synthase to form ATP.

Hence answer is c. transfer of electrons from cytochrome c to O2.
