Answer:
The correct answer is 3 phosphate groups.
Explanation:
ATP is a molecule that is found in both plants and animals and is basically the energy source of these living things. This molecule is responsible for saving energy for later use. Animals create ATP through the energy they can get from their food and plants through the energy absorbed in photosynthesis.
Its full name is Adenosine triphosphate and its composition is 3 phosphate groups. Said phosphates are salts made by the union of phosphoric acid with a base, in this case formed by adenine and linked to a ribose sugar.
Therefore the correct answer is: 3 phosphate groups.
