Question

The transition state (TS) complex in an enzyme - catalyzed reaction is than is the transition state complex in an uncatalyzed reaction. [*This is a multiple answer question, mark all that apply ] less stable higher in energy more stable lower in energy The allosteric enzyme. 3 - deoxy - D - arabino - heptulosinate - 7 - phosphate (DAHP) synthesizes is a branchpoint enzyme very early in the biosynthetic pathway that synthesizes aromatic amino acids (e. g. Phe). As this enzyme binds to its substrate it undergoes a slight conformational change allowing it to stabilize the substrate. Based on your knowledge of pathways and enzymes. which statement/s is/are TRUE? (J. Bacterid. Vol 94. No. 5) DAHP syn theta se is likely regulated by feedback inhibition when concentrations of aromatic amino acids are high. The pathway which DAHP helps to catalyze is an oxidative, catabolic pathway. DAHP syn theta se binds its substrate via the lock - and - key mechanism. all of the above In the following fictional metabolic pathway, product D acts as an effector molecule that downregulates enzyme 1. Note that product D binds reversibly and electrostatically to enzyme 1. Based on the information given, enzyme 1 Recognizes more than 1 substrate and thus creates pathway. is regulated by allosteric feedback inhibtion. is an interconvertible enzyme. all of the above
