What is the purpose of the sperm's midpiece?

Question

Quizplus · Accepted Answer

A spermatozoon is a single cell with two principal parts, a head and a tail. The head is basically the nucleus, containing 23 chromosomes, and an acrosome cap. The acrosome is a lysosome that contains enzymes that are eventually used to penetrate an egg. The tail contains a central flagellum used to propel the sperm on its journey. The section of the tail connected to the head (midpiece) is wider than the rest of the tail. This is because of the large mitochondria surrounding the flagellum. These mitochondria make use of any available oxygen to perform cellular respiration, which supplies ATP to energize the tail.
