Question

Which part of sperm enters the eggs in Humans?

Answer 1

Hint: Ovulation is the process of the release of ova or ovum from the uterus in a female reproductive system. During ovulation hormonal levels are up and down in the body. Ovulation is the mechanism of ovum and if fertilization does not occur, bloodshed in the form of menstruation. Menstruation occurs per month in a female. Ovulation occurs in the middle of the menstrual cycle.

Complete answer:
A rise in the levels of progesterone only- during the process the pituitary gland secretes two kinds of hormones one is LH and FSH. The levels of progesterone sometimes gradually increase.
The acrosomal part of the sperm enters the eggs in humans. The acrosomal protein mediating this recognition is called Binding, Binding is located specifically in the acrosomal process. Sperm binding does not happen over the entire egg surface. The receptor for the sperm binding into egg is vitelline membrane which envelops the eggs and protein portion of binding in a specific manner.
a rise in the levels of estrogen and progesterone hormones- the hormone helps in the release of follicles to shed off, the levels of hormones are very different. A rise in the levels of estrogen only- ovulation occurs when the luteinizing hormone secretes estrogen which supports the ovum to release. The estrogen levels are low at the time of fertilization.

Note:
Based on the ovulation surge, eggs or ovum are also covered by a plasma membrane or a cell membrane. In most animals’ special protective membranes are deposited outside the plasma membrane. These membranes are described as egg membranes. Based on the egg membrane, division is into the following types- primary egg membrane and secondary egg membrane.
