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).

What does RuBP mean?
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.
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.
In the light independent reactions carbon dioxide becomes fixed to?
In the light independent reactions, carbon dioxide becomes fixed to ribulose-1,5-bisphosphate (RuBP) with the help of the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) to form 3-phosphoglycerate in a process known as carbon fixation.
What is the loss of carbon-fixing activity of the enzyme RuBP carboxylase directly proportional to?
The loss of carbon-fixing activity of the enzyme RuBP carboxylase is directly proportional to the rate of photorespiration in the plant. As photorespiration increases, the enzyme's efficiency in fixing carbon dioxide decreases, leading to reduced photosynthetic productivity.
What requires carbon dioxide rubp ATP and nadph?
Light independent reaction, which occurs in the stroma.
What is an example of an Carbon dioxide acceptor?
ribulose bisphosphate (RuBP)
Process in which Carbon dioxide is attached to Rubp Molecules?
7
A carbon atom from carbon dioxide is used to change the five carbon sugar RuBP into?
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.
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 acceptor of carbon dioxide?
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.
What carbon atom from carbon dioxide is used to change the five-carbon sugar RuBP into what?
ATP.
What occurs when oxygen is attached to RuBp instead of carbon?
When oxygen is attached to RuBp (ribulose-1,5-bisphosphate) instead of carbon, it forms an unstable intermediate in the Calvin cycle called the RuBP carboxylation product. This product is quickly converted into two molecules of 3-phosphoglycerate by the enzyme Rubisco, initiating the fixation of carbon dioxide during photosynthesis.
What does RuBP mean?
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.
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 chemically bonds carbon dioxide to RuBP?
RuBisCo (Ribulose bisphosphate carboxylase)
A carbon atom from carbon dioxide is used to change the five-carbon sugar RuBP are formed?
To a six-carbon sugar :) Enjoy!
