[Solved] In opsonization with IgG, why would it be important that IgG react with the antigen BEFORE a phagocytic cell recognizes the antibody molecule? A) If the IgG is bound to the phagocyte BEFORE opsonization, it would most likely be ingested by the phagocyte before it could bind to a pathogen (it would be "naked," so to speak). B) Binding of IgG by phagocytes would block the antigen binding sites on the IgG molecules, preventing them from binding to the microbes. C) Binding of IgG by phagocytes changes their conformation-and by changing their protein conformation, their antigen binding sites are changed and they can no longer recognize their specific antigenic epitopes. D) Binding of antibody by phagocytes results in immediate release of protein-destroying enzymes to the outside of the cell. Since antibodies are proteins, they would be destroyed by these enzymes (and would then be unable to bind to their specific antigenic epitopes). Goodwill: An intangible asset that arises when a company acquires another company for a price higher than the fair value of its net identifiable assets. Equity Method: A method of accounting in which an investor recognizes its share of the profits and losses of an investee that it influences but does not control. Acquisition Differential: The difference between the purchase price of an acquired company and the fair value of its identifiable net assets. This differential is often allocated to goodwill or adjusted against specific assets. Impairment Loss: A financial write-down in book value due to impairment, reflecting a decrease in the recoverable amount of an asset beyond its current carried cost.
