Why, if the light phase is disturbed, the dark phase cannot be fully realized?

Light and dark phase are concepts that refer to the process of photosynthesis in plants. These are very important periods in photosynthesis. Both light and dark phases are very important. It is not difficult to guess that there is a light phase during the day and a dark phase at night. During the light phase, chloroplasts use carbon dioxide and water to form the structures of glucose molecules. During the dark phase, these structures are already used to create ATP. Accordingly, the plant will not receive energy during the dark phase without glucose.
