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.

- Consider the reaction. kp S P kg What effects are produced by an enzyme on the general reaction? AG for the reaction increases. The rate constant for the reverse reaction (kr) increases. The reaction equilibrium is shifted toward the products. The concentration of the reactants is increased. The activation energy for the reaction is lowered. The formation of the transition state is promoted.arrow_forwardThe graph displays the activities of wild-type and several mutated forms of subtilisin on a logarithmic scale. The mutations are identified as: • The first letter is the one-letter abbreviation for the amino acid being altered. • The number identifies the position of the residue in the primary structure. ⚫ The second letter is the one-letter abbreviation for the amino acid replacing the original one. • Uncat. refers to the estimated rate for the uncatalyzed reaction.

How would the activity of a reaction catalyzed by a version of subtilisin with all three residues in the catalytic triad mutated compare to the activity of the uncatalyzed reaction? It would have more activity, because the reaction catalyzed by the triple mutant is approximately three-fold faster than the uncatalyzed reaction. It would have less activity, because the reaction catalyzed by the triple mutant is approximately 1000-fold slower than the…arrow_forwardB Substrate Product AL Product Substrate Reaction progress- Reaction progress- omplete the passage describing the two reactions.
