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.
Home > Science > Biology > The Function Of Lysosomes The Function Of Lysosomes Lysosomes are organelles inside animal cells that are fully membrane-bound; they're not present in red blood cells, though, and fungi have a similar structure called vacuoles that serves the same purpose but actually is not considered a lysosome. Asfar as cellular components go, lysosomes are a relatively new discovery. First found by Belgian biologist Christian de Duve, winner of the 1974 Nobel Prize in Physiology or Medicine, lysosomes are both structurally and chemically sphere-shapedstructures that contain acid hydrolases.
