The stomata better be open so that plenty of carbon dioxide diffuses into the leaf and feeds into the Calvin cycle and makes sugars, specifically glyceraldehyde-3-phosphate.
In most plants stomata is usually opened on leaves to preserve water. As a result, CO2 is added during the Calvin Benson Cycle.
Plants that fix CO2 into organic acids at night when the stomata are open and carry out the Calvin cycle during the day when the stomata are closed are called CAM (Crassulacean Acid Metabolism) plants. CAM plants have adapted their carbon fixation process to avoid water loss during the day by keeping stomata closed, and perform photosynthesis during the night when conditions are cooler and less water loss occurs.
C4 plants keep their stomata closed during hot and dry conditions to reduce water loss through transpiration. By keeping their stomata closed during these times, C4 plants can minimize water loss while still being able to carry out photosynthesis efficiently using their unique carbon fixation pathway.
NADPH serves as a reducing agent in the Calvin-Benson cycle, providing electrons to drive the conversion of 3-phosphoglycerate into glyceraldehyde-3-phosphate. This reduction step ultimately leads to the production of glucose during photosynthesis.

It is widely known that CAM plants open their stomata at night time to fix the CO2 in form of organic acids. However, during the light reactions in daytime O2 is evolved while the stomata are closed and there is no way out. The question goes to the possible mechanism by which these plants can handle this high oxygen level during the daytime, while the stomata are closed. Do these plants have an oxygen accumulation and release system like that of CO2? Is such a mechanism studied or described elsewhere?
the final product of the calvin benson cycle used to produce glucose is?

By keeping their stomata closed during these times, C4 plants can minimize water loss while still being able to carry out photosynthesis efficiently using their unique carbon fixation pathway.
When stomata are closed, limiting factors for photosynthesis include a decrease in CO2 availability inside the leaf, leading to reduced carbon fixation and slowing down the Calvin cycle. This can also cause a build-up of oxygen produced during light reactions, leading to photorespiration and decreased photosynthetic efficiency.

They are usually closed during these periods so that they wont loose any water because of transpiration.
