AP Biology 1.3 A Describe the Chemical Reactions That Build and Break Biological Macromolecules Questions

Practise AP Biology 1.3.A questions by distinguishing hydrolysis from dehydration synthesis and tracking how water changes covalent bonds between monomers.

Exam points

identify water addition as hydrolysis that cleaves ATP or carbohydrate covalent bonds
identify water removal as dehydration synthesis joining monomers into polymers

To investigate how increases in environmental temperatures affect the metabolism of certain organisms, researchers incubated liver cells from toads at different temperatures and measured two markers of metabolic activity (Table 1): the rate of oxygen consumption and the rate of ATP synthesis.

Describe the role of water in the hydrolysis of ATP.
