The role of carbon dioxide,water and enzymes in photosynthesis is to make sugar and oxygen gas.
In light phase,obviously, it needs light energy and it occurs in thylakoids membranes. In this phase of photosynthesis there is a loss of energy along the electron transport chain to recharge ATP from ADP.In this process, light energy gets converted into chemical and finally ATP is produced.
In dark phase, does not require light and it occurs in stroma. In this phase of photosynthesis ATP and NADPH are used to produce energy and glucose sugar is synthesized from carbon dioxide and hydrogen.
