Which enzyme is in the human sperm head?
The spem head or acrosome cap contains digestive enzymes such as hyaluronidase and acrosin which are used to lyse the outer wall of the ovum during fertilization
What is the acrosome reaction?
The acrosome reaction must be completed before the sperm can fuse with the secondary oocyte, during the process of fertilisation. It occurs when the sperm comes into contact with the corona radiata of the secondary oocyte. Initally, perforations will develop in the acrosome, and then there will be point fusions of the sperm plasma membrane and the outer acrosomal membrane. The acrosome reaction is associated with the release of enzymes which facilitate fertilisation. The passage of sperm through the corona radiata is dependent on hyaluronidase, an acrosomal membrane, as well as tubal mucosal enzymes. Flagella action of the sperm also helps penetration of the corona radiata. Other important acrosomal enzymes include esterases, and lysin which causes lysis of the zona pellucida.
What is an acroblast?
An acroblast is a material derived from the Golgi apparatus from which the acrosome develops during spermatogenesis.
Why are there more egg and sperm cells produced during external fertilization than during internal fertilization?
Why are there generally more eggs and sperm cells produce during external fertilization thean internal fertilization
What unites during fertilization?
During fertilization the sperm unites with the egg. This typically occurs in the fallopian tube.
How does the human egg get fertilized?
Human fertilization is the union of a humanoid egg and sperm, usually occurring in the ampulla of the uterine tube. The result of this union is the production of a zygote, or fertilized egg, initiating prenatal development. Scientists discovered the dynamics of human fertilization in the nineteenth century.[1]The process of fertilization involves a sperm fusing with an ovum-usually following ejaculation during copulation. It is possible, but less common, for fertilization to occur without copulation, artificial insemination, or In vitrofertilization.[2][3][4] Upon encountering the ovum, the acrosome of the sperm produces enzymes which allow it to burrow through the outer jelly coat of the egg. The sperm plasma then fuses with the egg's plasma membrane, the sperm head disconnects from its flagellum and the egg travels down the Fallopian tube to reach the uterus.In vitro fertilization (IVF) is a process by which egg cells are fertilized by sperm outside the womb, in vitro.
The fusing together of two gametes at fertilization is?
Gametes fuse together during fertilization.
When are enzymes needed?
Enzymes are needed during the process of digestion.
Is fertilization possible during menstruation?
Not the least
What alleles are received during fertilization?
genotype
What process by which the egg cell and sperm cell unite during sexual reproduction?
No. Fertilization is the joining of an egg and sperm.
Which fuses with an egg during fertilization?
Semen or sperm
