The formation of glucose-6-phosphate from glucose is an endergonic reaction and is coupled to which of the following reactions or pathways?

The free energy derived from the hydrolysis of ATP can be used to perform many kinds of cellular work. Which of the following is an example of the cellular work involved in the production of electrochemical gradients?

Much of the suitability of ATP as an energy intermediary is related to the instability of the bonds between the phosphate groups. These bonds are unstable because __________.

Which of the following best characterizes the role of ATP in cellular metabolism?

When 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?

Which of these functional groups is known to be used for storing large amounts of chemical energy?a. amino groupb. carbonyl groupc. phosphate groupd. sulfhydryl group

The synthesis of ATP from ADP anda. 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.

In 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.
