Question

role of ATP in photosynthesis​

Answer 1

Answer: To make glucose, the plant needs to make bonds between the carbon, hydrogen and oxygen atoms, which in turn come from CO2 and water. Sunlight cannot be used directly by plant to make glucose. This is why the energy coming from sun in the form of photons is first turned into ATP, the energy of which is later used to make the bonds in the glucose molecule

Answer 2

In Photosynthesis, the role of ATP  is to provide the energy needed for carbohydrate synthesis in the dark reactions (also known as the Calvin-Benson-Bassham Cycle).
