Atp contains a large amount of energy because a) it captures energy from sunlight b) it receives energy from mitochondria c) it receives a phosphate group from adp d) it has high-energy phosphate bonds

The right option is; D) It has high-energy phosphate bonds  

ATP contains a large amount of energy because it has high-energy phosphate bonds.

Adenosine triphosphate (ATP) is an organic molecule that performs important roles as an energy transport molecule, a phosphate donor, and a signaling molecule within cells. ATP is made up of adenosine (an adenine ring and a ribose sugar), and three phosphate groups. ATP is an unstable molecule which hydrolyzes when it react with water to form ADP (adenosine diphosphate) and inorganic phosphate. The large amount of energy of ATP comes from the two high-energy phosphate bonds.
