Which molecule from the Calvin Cycle is used to replenish the five-carbon sugar RuBP which is used a the beginning of the cycles?
The molecule used to replenish RuBP in the Calvin Cycle is phosphoglycerate (PGA). PGA is converted to RuBP through a series of enzymatic reactions, allowing the cycle to continue and fix more carbon dioxide.
Which of the following chemicals is first produced by the Calvin cycle?
The first stable compound produced by the Calvin cycle is 3-phosphoglycerate (3-PGA), formed after carbon fixation of carbon dioxide with ribulose-1,5-bisphosphate (RuBP).
What can donate phosphate in the Calvin-Benson cycle?
In the Calvin-Benson cycle, the molecule that donates phosphate is ribulose bisphosphate (RuBP). This five-carbon sugar phosphate reacts with carbon dioxide in the presence of the enzyme ribulose bisphosphate carboxylase/oxygenase (RuBisCO) to form 3-phosphoglycerate (3-PGA). Additionally, ATP provides the energy and phosphate groups needed for the conversion of 3-PGA into glyceraldehyde-3-phosphate (G3P) during the cycle. Thus, ATP and RuBP are key contributors to the donation of phosphate in this process.
How many pgal molecules can there be during the Calvin cycle?
During the Calvin cycle, one molecule of 3-phosphoglycerate (3-PGA) is produced for every carbon dioxide molecule fixed. Thus, the number of 3-PGA molecules present during the Calvin cycle depends on the number of carbon dioxide molecules fixed in the process.
Where Three-carbon molecules of PGA are converted to G3P small sugar molecules by which come from the light reaction?
Three-carbon molecules of 3-phosphoglycerate (PGA) are converted to glyceraldehyde-3-phosphate (G3P) during the Calvin cycle in photosynthesis. This conversion occurs in the stroma of chloroplasts, where ATP and NADPH produced from the light reactions are utilized as energy and reducing power, respectively. G3P can then be used to form glucose and other carbohydrates, serving as essential energy sources for the plant.

The molecule used to replenish RuBP in the Calvin Cycle is phosphoglycerate (PGA). PGA is converted to RuBP through a series of enzymatic reactions, allowing the cycle to continue and fix more carbon dioxide.
The first stable compound produced from CO2 in the light-independent reactions is?
The first stable compound produced from CO2 in the light-independent reactions of photosynthesis is called 3-phosphoglycerate (3-PGA). This compound is formed through the fixation of CO2 by the enzyme Rubisco during the Calvin cycle.
How is RuBP is converted to PGA?
Ribulose bisphosphate (RuBP) is converted to 3-phosphoglycerate (PGA) through a reaction facilitated by the enzyme ribulose bisphosphate carboxylase/oxygenase (RuBisCO). During this process, RuBP combines with carbon dioxide in a reaction known as carboxylation, resulting in a six-carbon intermediate that quickly splits into two molecules of 3-phosphoglycerate (PGA). This reaction is a key step in the Calvin cycle, which is essential for photosynthesis in plants.
What is the first stable chemical formed by the Calvin Cycle?
G3p You have to capitalize the "p". "G3P" ~Jason
3-PGA is an abbreviation that stands for what?
3-PGA stands for 3-phosphoglycerate, which is an intermediate molecule in the Calvin cycle of photosynthesis.
What is 3-phosphoglycerate?
3-Phosphoglyceric acid (3PG), or glycerate 3-phosphate (GP), is a biochemically significant 3-carbon molecule that is a metabolic intermediate in both glycolysis and the Calvin cycle. This chemical is often termed PGA when referring to the Calvin cycle. 3-Phosphoglycerate is the resultant of the split of 6 carbon intermediate that is so unstable it splits instantly. And two 3-phosphoglycerate is produced for each molecule of CO2.
What is the source of energy for converting PGA into PGAl?
The source of energy for converting PGA (3-phosphoglycerate) into PGAL (glyceraldehyde-3-phosphate) is ATP (adenosine triphosphate). In the process of photosynthesis, ATP is utilized in the Calvin cycle to drive the conversion of PGA into PGAL. This conversion is catalyzed by the enzyme phosphoglycerate kinase while consuming ATP.
Why light independent phase of photosynthesis called c3 cycle?
The light-independent phase of photosynthesis is called the C3 cycle because the first organic compound produced during this phase contains three carbon atoms. This compound is 3-phosphoglycerate (3-PGA), which is formed in the Calvin-Benson cycle by fixing carbon dioxide from the atmosphere.
Which of the following chemicals is first produced by the Calvin cycle?
The first stable compound produced by the Calvin cycle is 3-phosphoglycerate (3-PGA), formed after carbon fixation of carbon dioxide with ribulose-1,5-bisphosphate (RuBP).
What Three carbon molecules of PGA are converted to energy rich G3 P sugar molecules by what?
Three-carbon molecules of phosphoglycerate (PGA) are converted to energy-rich glyceraldehyde-3-phosphate (G3P) sugar molecules through the process of photosynthesis, specifically during the Calvin cycle. This conversion requires the input of energy from sunlight and enzymes that catalyze the chemical reactions involved in the process.
What can donate phosphate in the Calvin-Benson cycle?
In the Calvin-Benson cycle, the molecule that donates phosphate is ribulose bisphosphate (RuBP). This five-carbon sugar phosphate reacts with carbon dioxide in the presence of the enzyme ribulose bisphosphate carboxylase/oxygenase (RuBisCO) to form 3-phosphoglycerate (3-PGA). Additionally, ATP provides the energy and phosphate groups needed for the conversion of 3-PGA into glyceraldehyde-3-phosphate (G3P) during the cycle. Thus, ATP and RuBP are key contributors to the donation of phosphate in this process.
