This diagram could represent a B. 
protein because if you look at the bonds you will see an R group and R groups are typically found in proteins.

Answer:
Mitochondria- often called the powerhouses of the cell — enable eukaryotes to make more efficient use of food sources than their prokaryotic counterparts. That's because these organelles greatly expand the amount of membrane used for energy-generating electron transport chains.

Answer:
A) 6
Explanation:
Complex III of the electron transport chain transfers four protons across the membrane during aerobic respiration, per pair of electrons. In the other hand, complex IV is responsible for transporting two protons (per pair of electrons) across the membrane. 
If the given compound injects a pair of electron into complex III,  four protons will accumulated due to complex III activity and then two more protons as these electrons move forward to complex IV. This means a total of 6 protons being transported to intermembrane space.
