15.4) a) Name the products of the dephosphorylation of ATP reaction shown below. NOTE: You do not need to draw the structural formulas of the products, just name them or use their abbreviations. ANSWER: inorganic phosphate (P₁), H+, and adenosine diphosphate (ADP) NH₂ NH₂ H₂O + +4 O-P-O- O -OCH₂ H H O adenosine triphosphate (ATP) H OH OH N N H O -OH + H+ 0-P inorganic phosphate (P₁) 0° O 0 OCH₂ H H H H OH OH adenosine diphosphate (ADP) b) Does the dephosphorylation of ATP reaction require energy or release energy? Energy is released from ATP when it is converted to ADP. This energy is used by organisms to drive energy-requiring reactions or physical processes that would otherwise not occur spontaneously. One way that energy can be released from ATP is by reacting it with H₂O to form ADP, inorganic phosphate, and an H+ ion. Although this reaction is spontaneous (AG is negative), the reaction rate is quite slow, therefore organisms employ enzymes in order for the reaction to proceed at a useful rate.

Acid phosphatases are an important group of enzymes that can be detected in human blood serum. Under slightly acidic conditions (pH 5.0), this group of enzymes can hydrolyze biological phosphate esters as follows: R-O-P-O;² + H 20 → R-OH + HO-P-O;² Acid phosphatases are produced and can be detected in erythrocytes, kidney, spleen, the liver, and prostrate gland. The enzyme from the prostrate gland is clinically important because an increased activity in the blood is frequently an indication of cancer of the prostrate gland. Tartrate ion can strongly inhibit the phosphatase from the prostrate gland, but not acid phosphatases from other tissues. How can you use the information above to develop a specific
