Describe the process of photophosphorylation
WebCyclic photophosphorylation is a cycle where the electron is recycled. One of the components in the thylakoid membrane is a photosystem, which is packed with chlorophyl. The chlorophyl absorbs the light energy and uses it to excite the electron. The electron is then passed to an electron acceptor protein, which passes it along an electron ... Web1. The process of producing carbohydrates by turning light energy into chemical energy is known as photosynthesis. It can be found in the thylakoids of algae and cyanobacteria as well as in the chloroplasts of plants. It begins with carbon dioxide, light, and water and ends with glucose and oxygen. The pigment molecules absorb light, which ...

WebAug 21, 2024 · Interestingly, the process of photophosphorylation is very similar to oxidative phosphorylation. This process is used in photosynthesis. However, instead of using oxygen to create water, it uses water to create oxygen. Basically the opposite of oxidative phosphorylation, photosynthesis uses an electron transport chain of its own to … WebSep 18, 2016 · Photophosphorylation occurs during photosynthesis and oxidative phosphorylation during cellular respiration. Explanation: Both photophosphorylation and oxidative phosphorylation (oxphos) are processes cells use to make energy in the form of ATP. First the similarities: in both cases electrons are transferred through a series of …
WebADVERTISEMENTS: The following points highlight the two types of Photophosphorylation. The types are: 1. Cyclic Photophosphorylation and 2. Non … WebPhotophosphorylation can be either oxygenic (Fig. 4 A) or anoxygenic (Fig. 4 B and C).Oxygenic photophosphorylation is carried out by cyanobacteria and algae, wherein water serves as the electron donor, leaving O 2 as a waste product. Anoxygenic photophosphorylation is carried out by purple bacteria, green bacteria, and others …
WebIn photosystem I, the light energy absorbed by the antenna (mostly chlorophyll a) allows, in the course of a second photochemical reaction, the displacement of an electron from the chlorophyll of the reactive center (P 700) to a primary acceptor X of unknown nature, then to another iron-sulphur protein. WebApr 6, 2024 · Process of Photophosphorylation. The electrons enter into an excited state i.e. higher energy state when the reaction center chlorophyll receives light energy. This …
