Cyclic Electron Flow - Biology As Poetry
Non-cyclic Electron Flow (photosynthesis light …
Noncyclic Photophosphorylation uses both photosystems 1 and 2.
The electrons transport in a noncyclic manner.
The active reaction center uses P680.
Recent studies show that the cyclic electron flow ..
Photolysis, water splitting, is present.
Oxygen changes during the process.
Takes place in plants.
Uses only Photosystem 1
The reaction center is P700
The electrons travel in a cyclic manner
Photolysis is not present.
Oxygen does not change throughout the process.
Most often used by bacteria.
Steps That Lead to Phosphorylation
Photosynthesis is a two step process that consists of the light and dark reactions.
Photophosphorylation is the process of generating ATP from ADP , by proton motive force generated by the thylakoid membrane.
Photophosphorylation takes place during the light reaction step in photosynthesis.
In light reaction, the addition of phosphate in the presence of light is called photophosphorylation.
What are the differences between cyclic and noncyclic electron flow
Photosynthesis is a process where by energy from light is harvested and used to drive synthesis of carbohydrates from carbon dioxide and water. Photophosphorylation is a process where the light energy captured by the photosynthetic organisms is transformed into the phosphate bond energy of ATP. Components of photosystem I and II transfer the electrons from water to NADP. Second step of photosynthesis is called Calvin’s cycle and it is a dark reaction. There are two stages here, I and II. Stage I is carbon dioxide fixation and stage II is the regeneration phase. Photorespiration is the process wherein oxygen consumption occurs in illuminated temperature zone of plants under high oxygen and low carbon dioxide. C4 cycle is the pathway adopted by C4 plants to conserve the carbon dioxide released via photorespiration. It occurs in mesophyll cells.
