Each and every plant goes through either the Calvin cycle or the C3 cycle. In order to produce one molecule of glucose via the C 3 pathway, 18 molecules of ATP are necessary, but via the C 4 pathway, 30 molecules of ATP are necessary. Find the answer to any query you have about photosynthesis in higher plants by using:
Therefore, the answer that you are looking for is ″Twelve.″
How many additional molecules of ATP are needed?
The production of one molecule of hexose sugar by C3-plants requires 18 molecules of ATP, while the production of the same sugar by C4-plants requires 30 molecules of ATP. Therefore, in order to produce one molecule of hexose sugar, C4 plants require 12 more molecules of ATP above and beyond what is required by C3 plants.
How many ATPs are required in C3 and C4 plants?
In order to fix six CO2 molecules during photosynthesis’s C4 cycle, a total of thirty ATP molecules are required. In the cells that make up the bundle sheath, the C3 cycle also occurs as part of the C4 pathway. For 6CO2 to be repaired by the C3 cycle, 18 ATPs are needed.
What is special about C3 plants?
- Because C3 plants do not have to be concerned about the possibility of losing water, they are able to leave their stomata open for extended periods of time during the day.
- Stomata, which are very small holes found on plant leaves, are used by C3 plants to take in carbon dioxide during the Calvin cycle, which is part of the photosynthesis process.
- Carbon dioxide and sugar are brought together with the assistance of an enzyme known as RuBisCO.
How many ATP are formed in C3 pathway?
Products of the C3 Cycle During the reduction of 3-phosphoglyceric acid to glyceraldehyde-3 phosphate and during the regeneration of RuBP, three molecules of ATP and two molecules of NADPH are required. In order to produce one molecule of glucose, 18 molecules of ATP and 12 molecules of NADPH are used up.
Why C4 plants are more efficient in photosynthesis than C3 plants?
C4 plants have a higher rate of photosynthesis and a lower rate of photorespiration, which contributes to their superior efficiency compared to C3 plants. RuBisCO, also known as ribulose bisphosphate carboxylase oxygenase, is the primary enzyme that is involved in the Calvin cycle, which fixes carbon. It has a strong affinity for carbon dioxide as well as oxygen.
How is 30 ATP used in C4 cycle?
Therefore, in order to make one molecule of glucose or to fix six molecules of carbon dioxide, 6 x 5 = 30 ATP must be used.
How many ATP molecules are required for the synthesis of one molecule of glucose in C3 pathway?
The production of one molecule of glucose via the C3 route needs the use of 18 molecules of ATP, whereas the production of glucose via the C4 pathway requires the use of 30 molecules of ATP.
How many ATP and NADPH are used in c2 cycle?
Therefore, the options that make the most sense are 18 ATP, 12 NADPH, and 30 ATP and 12 NADPH.
How many ATP and NADPH are formed in C4 cycle?
C4 plants require 30 molecules of ATP and 12 molecules of NADPH2 in order to synthesize a single molecule of glucose.
What do C3 plants have?
C3 plants are plants that produce 3-phosphoglycerate as the first product of assimilating carbon dioxide during the process of photosynthesis. 3-phosphoglycerate is characterized by the presence of three carbon atoms.
How are C3 plants different from C4?
- The dark reaction of photosynthesis, also known as the C3 pathway or the Calvin cycle, is carried out by C3 plants.
- The dark reaction of photosynthesis is carried out by C4 plants via the C4 route, also known as the Hatch-Slack Pathway.
- These are plants that thrive during the chilly season and are typically found in locations that receive a lot of moisture.
- These plants thrive during the warm seasons and are typically found in arid regions.
How many major type of cells are involved in the carbon dioxide fixation process in C3 plants?
MESOPHYLL CELS ARE THE MOST IMPORTANT CELLS INVOLVED IN THE CO2 FIXATION PROCESS THAT TAKES PLACE IN C3 PLANTS.
How many ATP and NADPH molecules are required to fix 3co2 Moleculels in a C3 plant?
In C3 plants, the process of fixing three molecules of CO2 requires 9 molecules of ATP and 6 molecules of NADPH. For the fixation of three CO2 molecules in C4 plants, 15 ATP and 6 NADPH and 6 NADPH are required as sources of energy.
How many ATP molecules are produced in Calvin cycle?
To generate a single molecule of glucose would require six revolutions of the cycle, or 6 CO2 start text, C, O, end text, start subscript, 2, end subscript, 18 ATP, and 12 NADPH.
How many additional molecules of NADPH are there?
The amount of energy necessary for the synthesis of one mole of hexose via the C3 and C4 route is, in addition to the 12 molecules of NADPH2 that are required. >> Where exactly are the ATP and NADPH molecules put to use?
