Multiple ChoiceWhen 1 mole of ATP is hydrolyzed in a test tube without an enzyme, about twice as much heat is given off as when 1 mole of ATP is hydrolyzed in a cell. Which of the following best explains these observations? 1185views
Multiple ChoiceThe formation of glucose-6-phosphate from glucose is an endergonic reaction and is coupled to which of the following reactions or pathways? 1628views
Textbook QuestionThe synthesis of ATP from ADP and a. stores energy in a form that can drive cellular work. b. involves the hydrolysis of a phosphate bond. c. transfers a phosphate, priming a protein to do work. d. is an exergonic process.881views
Textbook QuestionIn Figure 8.10, the energetic coupling of substrate phosphorylation and an endergonic reaction are shown. If the hydrolysis of ATP releases 7.3 kcal of free energy, use the graph in this figure to estimate what you would expect the ∆G values to be for the uncoupled reaction and the two steps in the coupled reaction. 683views
