Mаtch the wоrds highlighted in red in the twо pаrаgraphs belоw to the correct terms. Not all terms will be used.  ATCase is an allosteric enzyme that catalyzes the first step of pyrimidine formation. This first step involves the transfer of carbamoyl phosphate to the substrate, __________, to form "product A". "Product A" goes on to form (after several additional steps) a pyrimidine-based nucleoside triphosphate such as CTP. Early studies showed that the rate of formation of "product A" decreased as the concentration of the final product, CTP, increased. This is an example of ___________, a mechanism that prevents a pyrimidine surplus. In this scenario, CTP is acting as a ___________ effector of ATCase. At the same time, adenosine triphosphate (ATP), an end product of the parallel purine biosynthetic pathway, can act to ____________  ATCase activity. ATP is acting as a _____________ effector of ATCase. Ultimately, the interplay between CTP, ATP, and ATCase ensures an appropriate balance of purines and pyrimidines within the cell.  ATCase is a textbook example of a molecule under allosteric regulation. The initial binding of one or more substrates to one active site in the enzyme results in conformational changes that increase the likelihood that the enzyme will bind more substrate. Furthermore, binding of ATP to an allosteric site of the enzyme also increases the likelihood that the enzyme will bind more substrate. The conformational change of ATCase that occurs following the binding of either substrate or ATP that results in even more substrate binding is an example of a phenomenon called ______________. For this phenomenon to be possible, ATCase must consist of ____________ subunit(s). As the substrate (or ATP) bind to ATCase, more of the enzyme transitions from the ____________ state to the ____________ state. The R ("relaxed") state is a ____________ state, while the T ("tense") state is a _____________ state. These states coexist within a dynamic equilibrium that is sensitive to substrate availability and allosteric regulation.
