during photosynthesis, energy from sunlight is used to start a reaction. And water.

Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen gas

Explanation:

Each molecule of glucose essentially “stores” up to 38 molecules of ATP which can be broken down and used during other cellular reactions. ATP, or adenosine triphosphate, is the form of chemical energy cells use to function.
