In a first pregnancy, Rh sensitization is not likely. Usually, it only becomes a problem in a future pregnancy with another Rh positive baby. During that pregnancy, the mother's antibodies cross the placenta to fight the Rh positive cells in the baby's body.
Definition of Lysosome. Lysosome: An organelle (a little organ) in a cell containing enzymes that degrade macromolecules (large molecules) and other items (such as bacteria) taken up by a cell during the process of endocytosis.
Cells produce waste like all living things. The lysosomes are the garbage disposals of the cell. When a part of the cell becomes damaged or obsolete, it is moved to the outer edge of the lysosome. The membrane of the lysosome opens and the molecule is moved into the lysosome.Once inside, the digestive enzymes produced by the lysosome break down the molecule.After it is has been completely broken down, the lysosome opens to release the remains back into the cell in the form of a vesicle that the cell can expel through its membrane.ysosomes are organelles found inside all cells. In this lesson, you will learn about the structure and function of lysosomes to gain a better understanding of them.
