What chemical change occurs to ATP when it reacts with water and releases energy?
A
ATP is converted to ADP and inorganic phosphate.
B
ATP is converted to NADH and FADH2.
C
ATP is converted to glucose and oxygen.
D
ATP is converted to AMP and two inorganic phosphates.
Verified step by step guidance1
Identify the structure of ATP (adenosine triphosphate), which consists of adenosine and three phosphate groups.
Understand that the hydrolysis of ATP involves the breaking of the bond between the second and third phosphate groups.
Recognize that when ATP reacts with water (hydrolysis), it loses one phosphate group, resulting in the formation of ADP (adenosine diphosphate) and an inorganic phosphate (Pi).
Note that this reaction releases energy, which is used by cells to perform various functions.
Conclude that the chemical change occurring is the conversion of ATP to ADP and inorganic phosphate, not the other options provided.
