Effects of enzymes on aging and related diseases Enzymes How enzyme catalyze a chemical reaction Enzymes are biological catalysts , catalysts are those substances which can alter the speed of chemical reactions.There are positive and negative catalysts, positive catalysts speed up chemical reactions where as negative catalysts decreases the rate of chemical reactions.Enzymes are positive catalysts, which accelerate chemical reactions in our body.Enzymes are basically proteins ,made up of long chains of amino acids .Enzymes are discovered in 1897 by a German biochemist Eduard Buchner , he got Nobel prize in chemistry in 1907 for his discovery of cell-free fermentation . He showed that an enzyme named zymase extracted from yeast cells can break up sugar into alcohol and carbon dioxide.There are about 40,000 different enzymes present in our body ( these number may increase because every day new enzymes are discovering )each enzyme catalyze a different chemical r

Replication and new virion formation
Generally all viruses are intracellular parasites,it replicate only after infecting a host cell, corona virus have bigger genome when compared to other viruses such as HIV viruses,influenza viruses,Ebola virus,etc.The genome consist of four structural proteins and eight gens for small accessary proteins and a replicase gene,when corona virus enter in to the cell it's RNA look like messenger RNA(mRNA),which tells the cell what protein to make,as soon as RNA get into the cell protein making machinery begins to starts reading the viral genes,and making the proteins what they describes,after the cell made both proteins RNAs some of the RNA molecules get wrapped up with copies of the neucleocapsid proteins and then they are provided with envelop made of lipids,the assembling process takes place in the cellular work shop called Golgi apparatus,a cell may makes 100-1000 virions in this way,these virions enter other cells or body.
Precautions
If you touch contaminated surface wash your hands,don't touch your mouth eye or nose before washing hands,personal contacts is the most common reason for spreading the disease.
Vaccines
Vaccine development is underway,it will take at least 12-18 month to get any approved and effective vaccine for COVID-19,it is heard that now a days doctors are using hydroxychloroquinin(the old drug that used for malaria)along with Azithromycin.
