Homework Answers
Photosynthesis is an important process that is performed by plants through which light energy is converted and stored in the form of chemical energy. This chemical energy is stored in the form of carbohydrates in the plants and utilized by all living organisms to survive and perform their activities. In plants, photosynthesis takes place in a specialized organelle called the chloroplast. Photosynthesis consists of two reactions and classified on their dependence on the presence of sunlight: light-dependent reaction takes place in the thylakoid membrane of the chloroplast in the presence of sunlight. During day time light energy is captured by pigments chlorophyll present in the chloroplast. Through a series of redox reactions, the energy is stored in the form of ATP and NADP is reduced to NADPH. The reaction takes place in the presence of light, therefore also called light reaction, and during this process, water molecules split (photolysis) to transfer the electron to chlorophyll and oxygen molecules generated. Light-independent reaction takes place in the stroma of the chloroplast and does not require light, therefore also known as dark reactions. The ATP and NADPH produced in the light reaction are used in dark reactions for the fixation of carbon dioxide into sugar (glucose).
