Which part of sperm cell is responsible for locomotion and in which way sperm cell generates energy for the locomotion?
The flagellum is a long, whip-like cellular appendage that is used for with the help of energy generated by mitochondria.
The flagellum is a long, whip like cellular appendage that is used for locomotion. A sperm cell uses its flagellum in a whip-like fashion, lashing it back and forth to propel the sperm forward. Now, you may be wondering where the sperm cell gets the energy to whip a long flagellum back and forth so vigorously. After all, the nucleus contains very little besides DNA, and the acrosome doesn't contain any mitochondria to provide energy. That just leaves the flagellum itself. Sure enough, a portion of the flagellum right here is surrounded by mitochondria that provide the ATP or power for the whipping motion.
