Unformatted text preview: produce NADPH the light dependent reactions are stepping stones to the end goal of photosynthesis which is the production of sugar ATP and NADPH are used to power the synthesis of glucose in the light-independent reactions otherwise known as the Calvin cycle Photosynthesis If it gets too hot, plants close their stomates to conserve water This results in carbon dioxide not being able to enter and oxygen nto being able to leave Carbon dioxide is used to make sugar, so its levels decline Oxygen builds up With carbon dioxide levels declining the calvin cycle is lsowed down or stopped To make matters worse, rubisco is also an oxidase, so it can bind oxygen instead of carbon dioxide which it adds to the calvin cycle instead of carbon dioxide The product splits and produces carbon dioxide (like respiration_) but no ATP Because it occurs in the light and consumes oxygen, this process is called photorespiration...
