RuBP and CO2 form 2 molecules of G3P (glyserate 3 phosphate) in calvin cycle with aid from the enzyme rubisco.
The carbon atom from carbon dioxide is used to change the five carbon sugar RuBP into two three-carbon molecules. This process is known as carbon fixation and occurs during the Calvin cycle of photosynthesis. The three-carbon molecules produced are further processed to create glucose and other organic compounds.
If the supply of carbon dioxide is reduced, the concentration of RuBP (ribulose-1,5-bisphosphate) will increase as it accumulates without being converted into GP (glycerate-3-phosphate). On the other hand, the concentration of GP will decrease since there will be fewer reactants available for its formation in the Calvin cycle.
Carbon fixation involves the addition of carbon dioxide to organic compounds, such as ribulose-1,5-bisphosphate, in the Calvin cycle of photosynthesis. This process requires energy from light to convert the carbon dioxide into sugars that plants can use for growth and energy storage.
Ribulose-1,5-bisphosphate, the full name of RuBP, contains a total of 10 carbon atoms. The prefix "ribulose" indicates the sugar backbone, while "1,5-bisphosphate" suggests the presence of two phosphate groups on the first and fifth carbon atoms of the ribulose molecule.
Glyceraldehyde 3-phosphate produced during the Calvin cycle is used to regenerate RuBP (ribulose-1,5-bisphosphate), which is essential for the continuation of the cycle. This process involves a series of enzymatic reactions that ultimately allow the cycle to produce glucose and other carbohydrates needed by the plant for energy and growth.
The acceptor of carbon dioxide in photosynthesis is ribulose-1,5-bisphosphate (RuBP) in the Calvin cycle. RuBP combines with carbon dioxide in the presence of the enzyme RuBisCO to form an unstable 6-carbon compound, which eventually leads to the production of sugars.
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.
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.

The five-carbon compound that combines with CO2 in the Calvin cycle to form glucose is called ribulose-1,5-bisphosphate (RuBP). RuBP reacts with CO2 in a series of reactions facilitated by the enzyme rubisco to produce a six-carbon compound, which eventually leads to the synthesis of glucose.
RuBP stands for ribulose-1,5-bisphosphate. It is a five-carbon molecule involved in the Calvin cycle, a series of reactions in photosynthesis where carbon dioxide is converted into glucose. RuBP is regenerated during the cycle to ensure its continuous availability for fixing carbon dioxide.

To a six-carbon sugar :) Enjoy!
The joining of carbon dioxide to RuBP occurs in the Calvin cycle, specifically in the enzyme-mediated step called carbon fixation. This process is catalyzed by the enzyme RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase).
