In the process of photosynthesis, oxygen is produced from the photolysis of water. The photolysis of water occurs when light is used to renew split water and adenosine triphosphate, also referred to as ATP. When plants convert light energy into chemical energy, it is called photosynthesis. During the photosynthesis process sometimes oxygen is a waste product.
Photolysis of water is a light-dependent process that happens in the granum. By using the ATP, reduction can occur through carbon dioxide being turned into carbohydrates. The thylakoid membrane is where all non-light dependent processes occur. There are many factors that help to improve the photosynthesis process. If certain light conditions or temperature conditions are not met, it can result in the failure of photosynthesis occurring correctly.
