Web11. What is the mechanism by which the AIDS virus causes deficiency of immune system of the infected person? Solution: Upon managing to enter the body, this virus enters into macrophages, where the RNA genome of the virus duplicates for the formation of viral DNA by the action of the reverse transcriptase enzyme. The viral DNA is then incorporated WebThe enzyme action basically happens in two steps: Step1: Combining of enzyme and the reactant/substrate. E+S → [ES] Step 2: Disintegration of the complex molecule to give the product. [ES]→E+P. Thus, the whole catalyst action of enzymes is summarized as: E + S … Lipase enzyme breaks down dietary fats into smaller molecules known as glycero…
