The endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat. It may be a chemical process, such as dissolving ammonium nitrate in water, or simply the melting of ice cubes.
For women, the possibility of pregnancy begins in the ovaries. A woman is born with 1 to 2 million eggs, more than a lifetime's supply. The eggs begin dying off almost immediately and she never produces more. The average egg lives only about 24 hours, so it has to be fertilized soon for pregnancy to happen. If it doesn't get fertilized on time, it either dissolves or is absorbed by the body. When an egg is fertilized, its own genetic material and the genetic material of the sperm that got to the egg first combine to create a new cell that starts dividing rapidly. A woman isn't actually pregnant until that new bundle of cells (called the embryo) travels down the fallopian tube and attaches to the wall of the woman's uterus. The average pregnancy lasts for 38 weeks from the date you conceive (called conception). However, doctors usually date your pregnancy from the first day of the woman's last menstrual period. Using this method, a pregnancy is said to last 40 weeks, or 280 days.

Explanation:
An efficient derived from constitutive proteasome is called immunoproteasome. Its expression is highly visible in immune cells. It has an important role in immune system which is to degrade proteins of viral origin and intracellular proteins into smaller proteins. (See image for more detailed explanation)
