Textbook Question

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.

Verified step by step guidance

Identify the process being described: the synthesis of ATP from ADP.

Recall that ATP (adenosine triphosphate) is the primary energy carrier in cells.

Understand that the synthesis of ATP from ADP (adenosine diphosphate) involves the addition of a phosphate group.

Recognize that this process stores energy in the newly formed phosphate bond, which can be used for cellular work.

Determine which option correctly describes the synthesis of ATP: storing energy, not hydrolysis or exergonic processes.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

ATP Synthesis

ATP synthesis refers to the process of forming adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and inorganic phosphate (Pi). This process is crucial for storing energy in cells, as ATP serves as the primary energy currency, enabling various cellular functions and activities.

Phosphate Bond Hydrolysis

The hydrolysis of a phosphate bond involves the breaking of a high-energy bond in ATP, releasing energy that can be used for cellular work. This reaction typically results in the conversion of ATP to ADP and Pi, highlighting the dynamic nature of energy transfer within biological systems.

Exergonic vs. Endergonic Processes

Exergonic processes are reactions that release energy, while endergonic processes require energy input. The synthesis of ATP from ADP is an endergonic process, as it requires energy to form the high-energy phosphate bonds, contrasting with the exergonic hydrolysis of ATP that releases energy for cellular activities.
