ATP Study Prep Brooklynn Available on Pearson+ CONCEPT: ATP Recall: Adenosine Triphosphate (ATP ): a Naclestickenergy molecule used to "power" cellular activities. . There are 3 primary components of an ATP molecule: Monome 1 Chain of _phosphate groups 21R bose sugar 3 1 adenine _nitrogenous base. .ATP Hydrolysis: process of breaking bonds between AT groups generating chemical energy ADP. Polymer Sometimes ADP can be hydrolyzed to form AMP. EXAMPLE: ATP structure hydrolysis. Process Adenosine Triphosphate ( A IP) ATP ADP _ AMP 3 Adenine P-P-P _ ATP NH2 HO P-P o- CH2 ADP P ENERGY 3 Phosphate Group OH OH 1 (3 Phosphate Groups) P ENERGY 2 Ribose Sugar PRACTICE: Which of the following statements is true? ay ADP contains more potential energy than ATP. b) Following hydrolysis, ATP can give off one phosphate group and usable energy, whereas ADP cannot. c) The energy produced by ATP comes from the breaking of the bond between two phosphate groups. AMP and ADP contain the same amount of potential energy. PRACTICE: Which of the following is the most correct interpretation of the figure? a) Energy from food sources can be used directly for performing cellular work. ATP Energy from Energy for b) ADP + Pi are a set of molecules that store energy. Food Cellular Work c) ATP is a molecule that acts as an intermediary to store energy for cellular work. P + ADP d) Pi acts as a shuttle molecule to move energy from ATP to ADP. Page 1
