WebSubstrate affinity. In non- competitive inhibition, the substrate (S) and inhibitor (I) have equal potential to bind to the free enzyme (E). The inhibitor forms a ternary complex with enzyme-substrate (ES) whereas the substrate will form another ternary complex with enzyme-inhibitor (El). Since the non- competitive inhibitor had no effect on ... WebSpecificity constant. In the field of biochemistry, the specificity constant (also called kinetic efficiency or ), is a measure of how efficiently an enzyme converts substrates into products. A comparison of specificity constants can also be used as a measure of the preference of an enzyme for different substrates (i.e., substrate specificity ... look up driving record online freeWebMar 5, 2024 · Affinities of enzymes for substrates vary considerably, so knowing KM helps us to understand how well an enzyme is suited to the substrate being used.
