The addition or removal of phosphate groups from ATP is a fully reversible reaction, and the way this reversibility facilitates the use of ATP as a coupling agent for cellular reactions. Introduction: There are two types of reactions in all cells, anabolic and catabolic: Anabolic reaction (formation of large complex from simple ones) is an endergonic reaction with positive ∆G (change in free energy), which requires energy to form a big complex. This energy is provided by ATP (adenosine try phosphate), which is formed in the cell during catabolic reaction (break down of a complex molecule to form new small molecules). The exergonic reactions with negative ∆G release energy and this energy is stored in the form of ATP in the cell.

Consider the analogy of the jiggling box containing coins that was described on page 85. The reaction, the flipping of coins that either face heads up (h) or tails up (T), is described by the equation h ↔ T, where the rate of the forward reaction equals the rate of the reverse reaction.a. What are ΔG and ΔG° in this analogy? b. What corresponds to the temperature at which the reaction proceeds? What corresponds to the activation energy of the reaction? assume you have an “enzyme,” called jigglase, which catalyzes this reaction. What would the effect of jigglase be and what, mechanically, might jigglase do in this analogy?

As a result of an experiment following measurements were obtained from a cell: ATP concentration of 0.5 mM, ADP concentration of 0.1 mM, inorganic phosphate (Pi) concentration of 2 mM. Under these conditions calculate the actual free energy (AG) of the reaction of hydrolysis of ATP to ADP and Pi. (The standard energy (AG°) of ATP = -31 kJ/mol; RT = 2,58 kJ/mol) Select one: O a. -28 kJ/mol O b. -33 kJ/mol OC. -19 kJ/mol O d. -42 kJ/mol
