WebWhen a photon of light energy reaches a reaction center chlorophyll molecule, what becomes excited? a. a molecule of water vapor; b. an electron; c. a carbon dioxide … WebApr 24, 2024 · Photosynthesis is the process by which certain organisms, including plants, create sugars from the carbon dioxide in the air and the oxygen atom of water. The energy that drives this process comes from light. There are two phases of photosynthesis, the light reactions and the light-independent reactions, also called the Calvin cycle.

Des photosystèmes … WebJul 15, 2024 · There are different types of photosynthesis, including C3 photosynthesis and C4 photosynthesis. C3 photosynthesis is used by the majority of plants. It involves producing a three- carbon compound called 3-phosphoglyceric acid during the Calvin Cycle, which goes on to become glucose.
WebWhen a plant absorbs light energy for photosynthesis, it absorbs it in the form of photons, which are electromagnetic bundles of energy. Chloroplasts in the cells of the plant’s leaves contain a specialized greenish pigment called chlorophyll, which aids in … WebPhotosynthesis consists of a number of photochemical and enzymatic reactions. It occurs in two stages. During the light-dependent stage (“light” reactions), chlorophyll absorbs light …

Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are … See more Most photosynthetic organisms are photoautotrophs, which means that they are able to synthesize food directly from carbon dioxide and water using energy from light. However, not all organisms use carbon dioxide as a … See more In the light-dependent reactions, one molecule of the pigment chlorophyll absorbs one photon and loses one electron. This electron is taken up by a modified form of chlorophyll called pheophytin, which passes the electron to a quinone molecule, starting … See more Calvin cycle In the light-independent (or "dark") reactions, the enzyme RuBisCO captures CO2 from … See more Early photosynthetic systems, such as those in green and purple sulfur and green and purple nonsulfur bacteria, are thought to have been anoxygenic, and used various other molecules than water as electron donors.
