Ribulose bisphosphate (RuBP) captures carbon dioxide (CO₂) during the process of photosynthesis in plants. It serves as the substrate for the enzyme ribulose bisphosphate carboxylase/oxygenase (RuBisCO), which catalyzes the reaction between RuBP and CO₂, leading to the formation of 3-phosphoglycerate (3-PGA). This reaction is a crucial step in the Calvin cycle, allowing plants to convert atmospheric CO₂ into organic compounds.
What else can I help you with?
Carbon dioxide acceptor in the calvin-benson cycle is?
The carbon dioxide acceptor in the Calvin-Benson cycle is ribulose-1,5-bisphosphate (RuBP). RuBP is a 5-carbon compound that combines with carbon dioxide in the first step of the cycle to form an unstable 6-carbon compound, which eventually leads to the production of glucose.
What is the final product generated from the Calvin cycle at the end of the photosynthesis reactions?
The final product generated from the Calvin cycle at the end of the photosynthesis reactions is glucose, a simple sugar molecule that stores energy and is used by the plant for growth and metabolism.
What is the role of RuBp in Calvin cycle?
It is an enzyme that triggers the carboxylation (combining of carbon dioxide) of ribulose biphosphate in the stroma of chloroplasts in plants. This carboxylation is the first step of the light-dependant reaction that occurs in plants and this light-dependant reaction is the second stage of photosynthesis.
What is the meaning of rubp in biology?
In biology, RuBP stands for ribulose-1,5-bisphosphate, which is a key molecule in the Calvin cycle of photosynthesis. RuBP plays a critical role in capturing carbon dioxide from the atmosphere and initiating the process of carbon fixation to produce sugars in plants.
What hydrocarbons has five carbons?
Thousands if not millions of compounds have six carbon atoms.
Where does dark stage of photosynthesis take place?
The dark stage of photosynthesis takes place in stroma. The 1 molecule of glucose is converted into glucose by an enzyme called RUBP or RUBISCO.(RUBP=ribulose biphosphate enzyme , RUBISCO=ribulose biphosphate carboxylase oxygenase)
Carbon dioxide acceptor in the calvin-benson cycle is?
The carbon dioxide acceptor in the Calvin-Benson cycle is ribulose-1,5-bisphosphate (RuBP). RuBP is a 5-carbon compound that combines with carbon dioxide in the first step of the cycle to form an unstable 6-carbon compound, which eventually leads to the production of glucose.
How many carbons does rubilose diphosphate have?
Senior Biology books talk about ribulose biphosphate (RuBp). It is a 5 carbon sugar. The carboxylation of RuBp is one of a series of reactions known as the Calvin-Benson Cycle.
What is rubp?
RuBP stands for ribulose-1,5-bisphosphate, which is a molecule involved in the Calvin cycle of photosynthesis. It is a 5-carbon sugar that plays a key role in capturing carbon dioxide from the atmosphere to be converted into glucose.
What is the role of rubp in photosynthesis?
Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) is an enzyme that plays a key role in photosynthesis by catalyzing the first major step in carbon fixation, where it combines carbon dioxide and ribulose-1,5-bisphosphate to form 3-phosphoglycerate. This reaction helps plants convert atmospheric carbon dioxide into organic compounds that can be used for growth and energy production.
What is the last step of the Calvin cycle?
The last step of the Calvin cycle is regeneration of RuBP (Ribulose-1,5-bisphosphate) using ATP to continue the cycle. This is necessary to replenish the RuBP molecules that are used in the initial carbon fixation step.
What is the full form of RUBP?
Ribulose Biophosphate
What is an example of an Carbon dioxide acceptor?
ribulose bisphosphate (RuBP)
What is the final product generated from the Calvin cycle at the end of the photosynthesis reactions?

What chemically bonds carbon dioxide to RuBP?
RuBisCo (Ribulose bisphosphate carboxylase)
