Question
Chapter 32, Problem 12P
Interpretation Introduction
Interpretation:
The mechanisms for the synthesis of c-AMP from ATP in the presence of adenylyl cyclise and for the dissociation of cAMP and 5’-AMP by phosphodiesterase needs to be determined.
Concept Introduction:
Cyclic adenosine monophosphate (cAMP) is known to be a second messenger used for the intracellular signal induction. It is produced from adenosine triphosphate (ATP) in the presence of enzymes (g-proteins) attached to the metabotropic receptors. It releases the cAMP after the activation of the receptor.
It is important in all the main biological processes. It is mainly used for transfer of signal in between the cells of different organisms.

She then carries out the same experiment using ATP labeled with 32P in the central position, [ẞ-³2P]ATP, but the 32P does not appear in P; within such a short time. Which statements explain these results? Yeast cells reincorporate P; released from [ß-³2P]ATP into ATP more quickly than P¡ released from [y-³2P]ATP. Only the terminal (y) phosphorous atom acts as an electrophilic target for nucleophilic attack. The terminal (y) phosphoryl group undergoes a more rapid turnover than the central (B) phosphate group.
