The sperm penetrates the oocyte by first binding to the zona pellucida layer surrounding the oocyte. This triggers the acrosome reaction, releasing enzymes that help break down the zona pellucida. Once the sperm penetrates this layer, it fuses with the oocyte membrane to release its genetic material.

What does the sperm cell use to penetrate the egg?
The sperm cell uses an enzyme called hyaluronidase to break down the outer layers of the egg, allowing it to penetrate and fertilize the egg.
What destroys the sperm receptors on the surface of oocyte?
The acrosome reaction, triggered by the binding of sperm to the zona pellucida of the oocyte, releases enzymes that help degrade the zona pellucida. This process ultimately leads to the disruption of the sperm receptors on the surface of the oocyte, allowing only one sperm to successfully fertilize the egg.
Can sperm penetrate clothing to reach the skin?
No, sperm cannot penetrate clothing to reach the skin.
Can sperm penetrate through underwear?
No, sperm cannot penetrate through underwear. Underwear acts as a barrier that prevents sperm from passing through.
Can sperm penetrate clothing and result in pregnancy?
No, sperm cannot penetrate clothing and result in pregnancy. Direct contact with the vagina is needed for sperm to fertilize an egg.
What layers do sperm penetrate to fertilize the oocyte?
Sperm penetrate through the zona pellucida, an acellular glycoprotein layer surrounding the oocyte, to reach the oocyte membrane for fertilization. The sperm then binds to specific receptors on the oocyte membrane to release enzymes that help in penetrating the oocyte membrane to fuse with the oocyte.
What does contact of a sperm with the oocyte membrane cause?
The contact of a sperm with the oocyte membrane triggers a series of reactions that lead to the fertilization process. This includes the release of enzymes that help the sperm penetrate the oocyte, the fusion of the sperm and egg membranes, and ultimately the formation of a zygote containing a complete set of chromosomes from both parents.
Is It the secondary oocyte and not the egg that the sperm fertilizes?
Yes, it is the secondary oocyte that the sperm fertilizes. The secondary oocyte completes meiosis II to become a mature egg only after fertilization.
What does the sperm cell use to penetrate the egg?
The sperm cell uses an enzyme called hyaluronidase to break down the outer layers of the egg, allowing it to penetrate and fertilize the egg.
Does contact of a sperm with the oocyte membrane cause a completion of the second meosis?
Yes, contact of a sperm with the oocyte membrane triggers the completion of the second meiosis in the oocyte, leading to the formation of the female pronucleus. This process is essential for fertilization to occur.
What destroys the sperm receptors on the surface of oocyte?
The acrosome reaction, triggered by the binding of sperm to the zona pellucida of the oocyte, releases enzymes that help degrade the zona pellucida. This process ultimately leads to the disruption of the sperm receptors on the surface of the oocyte, allowing only one sperm to successfully fertilize the egg.
Can sperm penetrate clothing to reach the skin?
No, sperm cannot penetrate clothing to reach the skin.
Can sperm penetrate through underwear?
No, sperm cannot penetrate through underwear. Underwear acts as a barrier that prevents sperm from passing through.
Can sperm penetrate clothing and result in pregnancy?
No, sperm cannot penetrate clothing and result in pregnancy. Direct contact with the vagina is needed for sperm to fertilize an egg.
The cell commonly called the egg or ovum is more correctly called?
The egg or ovum is more correctly called an oocyte. It is referred to as an oocyte until it is fertilized by sperm, after which it becomes an embryo.
When does an oocyte complete meiosis II?
An oocyte completes meiosis II after it is fertilized by a sperm cell. This process results in the formation of a mature ovum (egg) with a haploid set of chromosomes.
Can sperm penetrate clothing?
Yes, sperm can potentially penetrate clothing, but the likelihood of this happening depends on various factors such as the type of fabric, the amount of sperm, and the force of ejaculation.
