You have extracted protease from culture filtrate of Termitomyces clypeatusgrown in potato dextrose broth.During partial characterization, youchecked protease activity at different temperature, pH. Surprisingly, the activity of proteolytic enzymein some isolates increased in presence of 0.6 mM PMSF inhibitor (serineprotease inhibitor). Later, you increased concentration to 6 mM, did not see reduction in activity. The same was observed in 0.1% gelatin zymography(activity staining) as well. However, inhibition of activity was observedwith metalloprotease and aspartic protease inhibitors EDTA and Pepstatin A respectively. Catalogue possible explanation of increase in activity in presence of PMSF

In a research study, a pharmaceutical company will be testing the effectiveness of a possible new vaccine for the Coronavirus. During this study, one group receives the actual medication while the other receives a syringe with saline solution (no medication). The group that receives the syringe without any medication is referred to as
