ATP is
A)an enzyme used widely in all kinds of cells.
B)a driver of both sides of the coupled reaction that forms ADP.
C)a molecule that carries a great deal of chemical energy in the bond between the terminal two phosphates.
D)the building block of all other cell structures.

Question

Quizplus · Accepted Answer

ATP is a molecule that carries a great deal of chemical energy in the bond between the terminal two phosphates. When this bond is broken, energy is released and the molecule is converted to ADP (adenosine diphosphate).

Note: Option A is incorrect as ATP is not an enzyme, but a molecule that can be used by enzymes. Option B is not a complete explanation as it only describes the relationship between ATP and ADP, but not the function of ATP. Option D is incorrect as ATP is not the building block of all other cell structures, but a molecule used for energy transfer within cells.
