WebA) A reaction may not occur at a detectable rate even though it has a favorable equilibrium. B) After a reaction, the enzyme involved becomes available to catalyze the reaction again. C) For S → P, a catalyst shifts the reaction equilibrium to the right. D) Lowering the temperature of a reaction will lower the reaction rate. WebCTP is also one of the final products of the synthesis reaction chain, and if CTP or UTP is too low compared to ATP, then the activity of ATCase is increased to compensate. Activity of the ATCase is regulated by shifting the enzyme from a tense, low-affinity state to a relaxed, high-affinity state. WebNov 16, 2016 · Cytidine triphosphate (CTP), which is an end product of the pyrimidine biosynthetic pathway, has a negative allosteric effect on ATCase activity, while adenosine triphosphate, ATP, has a positive … toddler\\u0027s fracture radiopaedia
