The correct answer is phosphorous but occurs in the form of a phosphate. ATP stands for Adenosine Triphosphate.
ATP is composed of three components. At the center of the molecule is found ribose, a sugar molecule which is the very same sugar that forms part of RNA. To one side of ribose is attached a base known as adenine. This base belongs to a group of molecules made of linked rings of both carbon and nitrogen atoms.
To the other side of ribose is attached a string of phosphate groups which are key to the energy carrying activities of ATP.
This answer is not mine, this answer is TaskMasters! Thank you :D
The 'greenhouse effect' is the warming of climate that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the 'greenhouse,' but blocking Earth's heat from escaping into space.
