Sperm in semen develop a speed of 5 cm / h, which in relation to their size is about 1.5 times faster than the speed of an Olympic swimmer. Explain what features of their organization determine such a speed of movement?
The mitochondria of a spiral structure is located in the neck of the sperm, it generates the energy necessary for active movement, the sperm receives most of the energy in the form of fructose, which is abundant in the ejaculate. The flagellum, consisting of 9 pairs of microtubules and a doublet in the center, is an organoid of active movement.
