The bond between the phosphate groups in ADP or the two bonds between phosphate groups in ATP are called high-energy bonds, because hydrolysis of a high-energy bond provides a large amount of free energy that can be used to drive other processes that would not otherwise occur. Adenosine can be linked to a chain of one, two, or three phosphate groups to form adenosine monophosphate (AMP), adenosine diphosphate (ADP), or adenosine triphosphate (ATP). The phosphorylation on the protein occurs on a serine or threonine residue in the protein. The cAMP cascade results in the phosphorylation of multiple enzymes. All these phosphorylations occur at the same time. cAMP is a derivative of adenosine triphosphate (ATP) and used for intracellular signal transduction in many different organisms, conveying. When glucose levels fall, a membranebound enzyme is activated as a glucose sensoradenylate cyclase. All the excess glucose goes through glycolysis. ![]() Adenosine nucleotides are involved in the energy metabolism of all cells. Cyclic adenosine monophosphate (cAMP, cyclic AMP, or 3',5'-cyclic adenosine monophosphate) is a second messenger, or cellular signal occurring within cells, that is important in many biological processes. It is a structural subunit of ribonucleic acid (RNA). The glucose-mobilizing effect of glucagon at fasting is mediated by cyclic AMP Nicolai J. a nucleoside composed of the pentose sugar d-ribose and adenine. ![]()
