\' Explain what steady state concentration means in the context of glycolysis, i.e., explain how the concentration of any intermediate in glycolysis stays the same when your physical activity level doesn\'t change, but the reactions are not in equilibrium. 5. Everyone has heard of ATP, but there is also GTP, UTP, and CTP, as well as many others. They are used in the synthesis of RNA, but have other roles as well. Use any resource you\'d like to and give one specific use of each of these four compounds that is neither part of RNA synthesis nor just a source of energy for a coupled reaction. 8 7 8 Solution Q. 2. Use of ATP other than RNA synthesis: The important role of Adenosin Triphosphate (ATP) is (i) in Na + /K + /Ca +2 ion pump system (ii) ATP is involved signal transduction by serving as substrate for kinases. Use of GTP (Guanosine-5\'-triphosphate) : GTP has an important role in \'Genetic Translation\'. During the elongation stage of translation, GTP is used as an energy source for the binding of a new amino-bound tRNA to the A site of the ribosome. Use of UTP (Uridine-5\'-triphosphate ) : UTP has an important role in receptor mediation. It is performed by extracellular binding to the P2Y receptors of cells. Use of CTP (Cytidine triphosphate): CTP acts as an inhibitor of the enzyme aspartate carbamoyltransferase, which is used in pyrimidine biosynthesis. .
