Enzyme A catalyzes the reaction S P and has a KM of 50 M and a Vmax of 100 nM s 1, Enzyme B catalyzes the reaction S Q and has a KM of 5 mM and a Vmax of 120 nM s 1 When 100 M of S is added to a mixture containing equivalent amounts of enzymes A and B, after 1 minute which reaction product will be more abundant P or Q

Question: Enzyme A catalyzes the reaction S P and has a KM of 50 M and a Vmax of 100 nM s-1, Enzyme B

Enzyme A catalyzes the reaction S → P and has a KM of 50 μM and a Vmax of 100 nM ∙ s-1, Enzyme B catalyzes the reaction S → Q and has a KM of 5 mM and a Vmax of 120 nM ∙ s-1. When 100 μM of S is added to a mixture containing equivalent amounts of enzymes A and B, after 1 minute which reaction product will be more abundant: P or Q?
