What is the first stable product of C4 cycle ? from

The first stable product is 3-phosphoglycerate. 2. The first stable product is oxaloacetic acid. 3. It occurs only in the mesophyll cells of the leaves. 3. It occurs in the mesophyll and bundle-sheath cells of the leaves. 4. It is a slower process of carbon fixation and photo-respiratory losses are high. 4 9. First stable product of C 4 plants is Photosynthesis in Higher Plants 10 Solution: In C 4 plants the first stable product is 4-C compound oxaloacetic acid. Phosphoenol pyruvate recieves C O 2 and produce it. In C 3 plants the RuBP recieves C O 2 and forms phosphoglyceric acid (a 3-C compound)

The C4 cycle is present only in C4 plants: 6: First stable product in C3 cycle is a 3 carbon (3C, hence the name) compound - Phosphoglyceric Acid (PGA). First stable product in C4 cycle is a 4 carbon (4C, hence the name) compound - Oxaloacetic Acid (OAA). The first stable product of photosynthesis is - This objective type question with answer for competitive exams is provided by Gkseries first stable product of ____ photosynthesis is a three-carbon sugar. C4 plant plant that fixes carbon dioxide to produce a C4 molecule that releases carbon dioxide to the Calvin cycle most common, process where first stable product of photosynthesis is a 3 carbon molecule (includes photorespiration) C4 photosynthesis. process where plant fixes carbon dioxide to produce C4 molecule that releases CO2 to calvin cycle (bundle sheath cells In the majority of the plants, the first stable intermediate of carbon dioxide reduction is a three-carbon compound. Hence, this type of carbon reduction is called as C 3 cycle. In C 3 cycle the initial carboxylation is brought about by RuBisCO, which carboxylates Ribulose- 1,5 bisphosphate (RUBP) into phosphoglyceric acid. The phosphoglyceric acid is later on reduced to phosphoglyceraldehyde.

CO2 assimilation during photosynthesis is 2 types: C3 pathway: In this, first stable product of CO 2 fixation is a C3 acid (3-phosphoglyceric acid - PGA). Melvin Calvin discovered this using 14C in algal photosynthesis. C4 pathway: In this, first stable product is oxaloacetic acid (OAA), a 4-carbon (C4) organic acid The first step in the NADP-ME type C 4 pathway is the conversion of pyruvate (Pyr) to phosphoenolpyruvate (PEP), by the enzyme Pyruvate phosphate dikinase (PPDK). This reaction requires inorganic phosphate and ATP plus pyruvate, producing PEP, AMP, and inorganic pyrophosphate (PP i). The next step is the fixation of C C3 plants produce phosphoglyceric acid as the first stable product of the dark reaction. It is a three-carbon compound. On the other hand, C4 plants produce oxalo-acetic acid as the first stable product of the dark reaction. It is a four-carbon compound The first stable product of this process is a four-carbon compound, hence the name. Moreover, there are two C4 cycle steps which every plant follow; these are - At first, when CO2 enters a mesophyll cell, phosphoenolpyruvate (PEP) carboxylase enzymes adds it to the three-carbon PEP. This produces a four-carbon compound called oxaloacetate 2. Calvin, Benson and others found that during photosynthesis, the first stable product in sugar formation is 3-phosphoglyceric acid, while Hatch and Slack showed that it is oxaloacetic acid. Comment on these contradicting observations. (2

Main Difference - C3 vs C4 Cycle. C3 and C4 cycle are two types of cyclic reactions that occur as the dark reaction of the photosynthesis.Photosynthesis is the production of simple organic molecules, glucose from inorganic molecules, carbon dioxide and water, using sunlight as the energy source. During photosynthesis, the light reaction is followed by the dark reaction However, C3 plants are unable to carry out photosynthesis when the stomata are closed and under very high light concentrations and low CO2 concentrations. materials », Effects of Rising Atmospheric Concentrations of Carbon Dioxide on Plants, Section 2: Environmental Dynamics and Drivers, Section 3: Systems Approaches to Managing our Food, Section 4: Food Systems and Sustainability, Module 5. These plants are termed as C4 plants because of the first stable photosynthetic product being a 4 carbon compound. Characteristics of C4 plants: Following are the characteristics of C4 plants: The C4 plants appear to be better equipped to withstand drought and are also able to maintain active photosynthesis under condition of water stress NEET Biology NCERT Unit 12 The process in which green parts of the manufacture or synthesize complex organic food substances using carbon dioxide and water in the presence of sunlight and release oxygen as a by-product. In this process, energy from the sun is converted into chemical energy. It is endergonic, anabolic and oxido-reduction process. Photosynthesis is important due to two reasons.

A pyruvate molecule is carboxylated by a pyruvate carboxylase enzyme, activated by a molecule each of ATP and water. This reaction results in the formation of oxaloacetate
  5. First stage: In CO2 Fixation, the CO2 that diffuses into the stroma of the chloroplast in mesophyll cells is added to the five-carbon acceptor ribulose-1,5-bisphosphate also called diphosphate phosphoglycerate or phosphoglyceric acid as the first stable product.
