ATP Synthase Molecules in Mitochondria Form Dimers That Are Localized

ATP synthase molecules in mitochondria form dimers that are localized mostly to sharp cristae ridges. What should happen if subunits of the synthase that are required for dimerization are mutated in yeast?

A) Oxygen consumption would drop
B) Cristae ridges would disappear
C) Cell growth would slow down
D) Monomeric ATP synthases would distribute randomly over the inner membrane
E) All of the above
