![]() ![]() ATP formed is utilized in the dark reaction of photosynthesis. ATP synthesized is utilized in various metabolic processes. ATP is formed by the conversation of light energy (photophosphorylation). The light energy is converted into chemical energy (in the form of carbohydrate) Besides, some energy is also lost in the form of heat. The energy locked in carbohydrates and other respiratory substrates is trapped in the ATP molecules on oxidation. It occurs only in the chlorophyll containing cells. In respiration, the carbohydrates are oxidised through a series of reactions and the energy released is trapped in ATP molecules.Ĭomparison between ATP synthesis in Respiration and Photosynthesis are as follows: It is bound in the chemical bonds of the carbohydrates. ![]() In photosynthesis, the radiant energy of the sun is converted into chemical energy. Photosynthesis is a process that converts light energy from the sun into organic compounds by using water from soil and carbon dioxide from the air in presence of chlorophyll. Respiration can be defined as the process by which living cells break down complex high energy food molecules into simple low energy molecules, releasing the energy trapped within the chemical bonds. Photosynthesis and respiration are two major processes by which both animals and plants can supply energy for continuing their life processes. Both involve exchange of gases and production of energy. ATP synthesis in both respiration and photosynthesis is possible by several redox reactions including oxidation and reduction reactions. Hint: Respiration and photosynthesis are the two important metabolic processes of the plant. ![]()
