The products of light dependent reactions are ATP, oxygen and NADPH. In this lesson, we'll learn how electrons get excited during the light-dependent reactions of photosynthesis, jumping off photosystem reaction centers like they were trampolines! They are light-dependent reactions and light independent reactions. The light-independent reactions can be summarized as follows: 12 NADPH + 18 ATP + 6 CO 2 yields C 6 H 12 O 6 (glucose) + 12 NADP + + 18 ADP + 18 P i + 6 H 2 O. … Light Dependent Reactions. The light-dependent reactions involve two photosystems called Photosystem I and Photosystem II. Rubisco can also catalyse a reaction between RuBP and oxygen to form one molecule of GP and one molecule of phosphoglycolate. Seeing how light energy can excite electrons which can be used to create ATP and NADPH (with oxygen as a byproduct). In plant cells, they mainly take place during the day because they work together with the light-dependent reactions, using their reaction products as reactants to make carbohydrates as food for the plant. The overall purpose of the light-dependent reactions is to convert light energy into chemical energy. The light dependent reaction is the initial step of the process of photosynthesis, by which plants can store energy from sun light.
