Overview. Photosynthesis changes sunlight into chemical energy, splits water to liberate O 2, and fixes CO 2 into sugar. Most photosynthetic organisms are photoautotrophs, which means that they are able to synthesize food directly from carbon dioxide and water using energy from light.
Aug 3, 2023 · Photosynthesis is defined as the process, utilized by green plants and photosynthetic bacteria, where electromagnetic radiation is converted into chemical energy and uses light energy to convert carbon dioxide and water into carbohydrates and oxygen.

•Many organisms make their own food through photosynthesis. Plants, algae, and some unicellular organisms do photosynthesis.
•Photosynthesis is powered by energy from sunlight. This energy is used to rearrange atoms in carbon dioxide and water to make oxygen and sugars.
•Carbon dioxide and water are inputs of photosynthesis. These inputs come from the environment.
•Oxygen and sugars are outputs of photosynthesis.
•The oxygen is released into the environment.
•The sugars can provide chemical energy. This energy can be used by the organism to live and grow. The sugars can also be used to build the organism’s structures, or they can be stored for later use.
Dec 13, 2019 · Oxygenic photosynthesis begins with light absorption, followed by excitation energy transfer to the reaction centres, primary photochemistry, electron and proton transport, NADPH and ATP synthesis, and then CO 2 fixation (Calvin–Benson cycle, as well as Hatch–Slack cycle).

When light energy is captured by the chloroplast, it, along with carbon dioxide and water, gets converted to ATP, NADPH, and oxygen (light-dependent reactions). The ATP and NADPH then enter the Calvin cycle and fuel the synthesis of molecules that eventually become sugar molecules.

Mar 24, 2024 · Photosynthesis is the process by which atmospheric carbon dioxide is assimilated and converted to glucose and oxygen is released. CO2 and H2O are utilised in the process. In the cellular respiration, glucose is broken down to CO2 and energy is released in the form of ATP, which is utilised in performing various metabolic processes.
