ATP is an important biological molecule that transports chemical energy within cells and powers many biochemical reactions.

Which of the following correctly describes the structure of ATP and how it provides energy?

• ATP contains a 5-carbon sugar, three phosphate groups, and an adenine base. Energy is released when the bond between the adenine base and the sugar is broken.

• ATP contains a 6-carbon sugar, two phosphate groups, and an adenine base. Energy is released when a single phosphate group is added to the existing two phosphate groups.

• ATP contains a 6-carbon sugar, three phosphate groups, and an adenine base. Energy is released when bonds within the 6-carbon molecule are broken.

• ATP contains a 5-carbon sugar, three phosphate groups, and an adenine base. Energy is released when the bond between the second phosphate group and third phosphate group is broken.
