Detailed explanation-1: -The sperm mitochondria produce energy for the movement of the sperm.
Detailed explanation-2: -Sperm, however, contain many mitochondria strategically placed where they can most efficiently power the flagellum.
Detailed explanation-3: -The midpiece of the sperm is packed with mitochondria. Mitochondria are organelles in cells that produce energy. Sperm use the energy in the midpiece to move.
Detailed explanation-4: -The typical mammalian sperm midpiece contains approximately 50–75 mitochondria with one copy of mtDNA in each.
Detailed explanation-5: -The force for flagellar movement is exerted by the sliding of outer-doublet microtubules driven by the molecular motors, the dyneins. Dynein activity is regulated by the radial spoke/central pair apparatus through protein phosphorylation, resulting in flagellar bend propagation.
