What provides the sperm with energy?
The tip of the sperm head is the portion called the acrosome, which enables the sperm to penetrate the egg. The midpiece contains the mitochondria which supplies the energy the tail needs to move.
Why do sperm cells need energy?
Key Issues. Sperm need energy to sustain motility and perform sperm function. Mid-piece and flagellum are the sites of energy production. Spermatozoa are capable of both aerobic and anaerobic glycolysis, and several glycolytic enzymes are localized along the fibrous sheath of the flagellum.
Which structure produce an energy source for sperm?
After emerging from the testes, sperm are stored in the epididymis, in which secretions of potassium, sodium, and glycerylphosphorylcholine (an energy source for sperm) are contributed to the sperm cells. Sperm mature in the epididymis.
Why is the structure of sperm important to its function?
The overall structure of the sperm makes it perfectly designed to carry out its function. The DNA, or biological information the sperm needs to pass on, is contained in its head. The tail of the sperm helps give it the momentum it needs to reach the egg cell, so it is able to create the embryo in the first place.
What food can make sperm thicker?

What makes up the nucleus of the sperm?
The head of the sperm contains the nucleus. The nucleus holds the DNA of the cell. The head also contains enzymes that help the sperm break through the cell membrane of an egg. The midpiece of the sperm is packed with mitochondria. Mitochondria are organelles in cells that produce energy.
How does sperm get from the sperm cell to the egg?
Upon reaching an egg, enzymes contained within the sperm acrosome are activated, enabling the sperm to traverse the thick coat surrounding the egg (the zona pellucida ); this process is known as the acrosome reaction. The membrane of the sperm cell then fuses with that of the egg, and the sperm nucleus is conveyed into the egg.
What is the role of mitochondria in sperm development?
As mitochondrial energy metabolism is a key factor supporting several sperm functions, these organelles host critical metabolic pathways during germ cell development and fertilization.
How is the acrosome involved in the fertilization of sperm?
For instance, with a number of its associated molecules, the acrosome is involved in the recognition of the oocyte (egg) to be fertilized. Once the sperm cell comes in contact with the diffusible molecules from the egg jelly, this stimulates the cell to swim towards the eggs.
