→Akshita who is a biology tutor was teaching photosystems to the students at her place. While explaining the topic light reaction said that, "Two of the three products of light reaction, ATP and NADPH are used to drive the reactions in the biosynthetic/dark phase." It has been verified by the fact that immediately after light becomes unavailable, the biosynthetic phase continues for some time and then stops; if light becomes available again, the process continues. Her brother, student of class XI was also listening the same and was remembering that he had listened the same from his biology teacher also. He interupped her sister and asked her to re-explain the whole process for the better understanding.
