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.
Activation takes place when the lysosome fuses with a specific organelle to form a hybrid structure. Lysosomes (lysosome: from the Greek: lysis; loosen and soma; body) are found in nearly all animal and plant cells.In plant cells vacuoles can carry out lysosomal functions. Lysosomes appear initially as spherical bodies about 50-70nm in diameter and are bounded by a single membrane.uick look: Lysosomes are membrane bounded organelles found in animal and plant cells. They vary in shape, size and number per cell and appear to operate with slight differences in cells of yeast, higher plants and mammals. Lysosomes contribute to a dismantling and re-cycling facility.
