Answer:
This question is incomplete but it can be answered based on general understanding.
The reaction is CALVIN CYCLE OR LIGHT-INDEPENDENT REACTION
Explanation:
The high energy batteries being referred to in this question IS ATP. ATP is an energy-storing molecule produced in the first stage or reaction of photosynthesis called LIGHT DEPENDENT REACTION. Photosynthesis, which occurs in two stages, produces ATP molecule in the first stage as a result of the charging of ADP into ATP.
The ATP molecule, which serves as a high energy battery, is used to power the second stage of photosynthesis called LIGHT INDEPENDENT REACTION OR CALVIN CYCLE in order to yield sugars.
