Answer #1

The secnario where the enzyme activity is dimnished where the identity of the molecule concerned is a typical case of competitive inhibition.Here the inhibitor closely has structural similarities with the susbtrate and can bind to the active site of the enzyme .This reduces the site availability for substrate and enzyme activity is reduced.

An other way is by allosteric inhibition in which the inhibitor binds to the allosteric site(site other than the active site) and changes the arrangement or the conformation of the active site and hence inhibits the susbstrate binding thereby stopping enzyme activity.

Adaptive immunity has several features that distinguish it from innate immunity. Specificity in that each adaptive immune response is induced by a particular antigen, or surface feature that generates an antibody. An innate immune response might be stimulated by a PAMP, while an adaptive immune response is stimulated by a single feature of a bacteria. In addition, cells of adaptive immunity, B and T cells, are allowed to proliferate under certain conditions to mount a defense, this feature is clonality...
