C3 And C4 Pathways
1. Difference Between C3 and C4 Pathway?
C3 and C4 cycle has two different stages of photosynthesis process which are connected to each other. C3 pathway involve only mesophyll cells but C4 plants involve mesophyll cell and bundle sheath cells both to fix carbon.
2. Which Plant Uses C4 Cycle As Their Pathways For Photosynthesis?
These are usually used by the tropical region plants. As there scarcity of water is in extreme condition, and these plants have turned them into water conservation. Such as sugarcane, maize, millets and sorghum.
3. What is simple term for C3 Pathway.
Pathway in which plant produces 3-carbon acid called as phosphoglyceric acid(PGA) as the first product during CO2 fixation. This pathway is known as Calvin cycle containing three steps, carboxylation, reduction and regeneration.
4. What is C4 Pathways in simple term?
Pathways in which initial carbon fixation occur in mesophyll cells and calvin cycle in bundle sheath cells are known as C4 pathways. PEP carboxylase attaches CO2 molecule to the three carbon molecule PEP, produces oxaloacetate which is a four carbon molecule.
5. What is the C4 Pathway also known as?
C4 pathway was also known by Marshall Davidson Hatch and Charles Roger Slack, in Australia, in 1966. While Hatch and Slack originally referred to the pathway as the “C4 dicarboxylic acid pathway”, it is sometimes called the Hatch–Slack pathway.
C3 and C4 Pathways
C3 and C4 are photosynthetic pathways present in terrestrial plants. C3 plants use the C3 pathway or Calvin cycle, and C4 plants use the C4 pathway, or Hatch-Slack pathway, for the dark reaction of photosynthesis. Photosynthesis is the process in which different bacteria like cyanobacteria and eukaryotes like green plants, and algae can convert solar energy to chemical energy. In this process, solar energy is absorbed and used to synthesize carbohydrates from carbon dioxide and water.
