Answer:
It contains enzymes that can break down intracellular waste to a certain degree it is responsible for some metabolic process like ATP production via glycolysis finally it aids the cytoskeleton/microfilaments in give the cell and its organelles stability/support.
 
        
                    
             
        
        
        
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.
