How does energy transformation happen in photosynthesis?

Question

Luna Cruz · Accepted Answer

During photosynthesis, solar energy is converted into chemical energy in the form of ATP molecules.

Solar energy is transformed into chemical energy during photosynthesis in the form of an ATP molecule's energy-rich bond. The terms "energy currency" refer to the molecules of adenosine triphosphate (ATP) and adenosine diphosphate (ADP), which are transformed into ATP molecules whenever energy is available in specific exothermic reactions of metabolism. Energy is stored in ATP molecules, which are converted into ADP molecules when the enzyme ATPase is present. This process releases energy when needed. Photo-phosphorylation is the process of synthesizing ATP molecules using solar energy during photosynthesis. These ATP molecules are used in the dark reaction (Calvin cycle) of photosynthesis, which is the result of photosynthesis' light reaction. The ATP molecules produced by photophosphorylation can be employed in additional metabolic processes. There are two different types of photophosphorylation: cyclic and non-cyclic. Solar energy is captured by chlorophyll molecules. There are two different kinds of photosystems in chlorophyll: photosystem I and photosystem II. After being excited, the electrons in the chlorophyll molecule of photosystem I travel through a sequence of electron carriers in the electron transport system that are arranged in decreasing energy levels. ADP molecules are converted into ATP molecules, but energy is lost in the process of electrons moving from higher energy carriers to lower energy carriers. Only the light reaction of photosynthesis—cyclic photophosphorylation—is the focus of photosystem I. NADPH2 is produced during Photo-system II electron transport in the presence of the enzyme NADP reductase, and it is utilized in the Calvin cycle reduction reaction. In addition to producing ATP molecules, both photosystems take part in non-cyclic photophosphorylation, which produces NADPH2.

undefined By absorbing sunlight through chlorophyll and using it to power the synthesis of glucose from carbon dioxide and water in the presence of enzymes, photosynthesis transforms light energy into chemical energy.
