The form of carbon dioxide used by the enzyme Rubisco is typically in its gaseous state (CO2) present in the atmosphere. Rubisco catalyzes the first major step of carbon fixation in the Calvin cycle, where CO2 is incorporated into a 5-carbon sugar (ribulose bisphosphate) to form 3-phosphoglycerate. This process is crucial for photosynthesis in plants, algae, and some bacteria.
What else can I help you with?
What molecules supply the carbon component of carbohydrates during the Calvin cycle?
Carbon dioxide molecules (CO2) supply the carbon component of carbohydrates during the Calvin cycle. Carbon dioxide is fixed by the enzyme RuBisCO to form intermediate molecules that eventually lead to the production of glucose and other carbohydrates.
Which enzyme is used during the Calvin cycle?
The primary enzyme used during the Calvin cycle is ribulose-1,5-bisphosphate carboxylase/oxygenase, commonly known as RuBisCO. This enzyme catalyzes the reaction of carbon dioxide with ribulose-1,5-bisphosphate (RuBP) to form 3-phosphoglycerate (3-PGA), the first stable product of the cycle. RuBisCO plays a crucial role in fixing atmospheric carbon into organic compounds during photosynthesis.
A substance that acts as a catalyst during photosynthesis is?
The substance that acts as a catalyst during photosynthesis is an enzyme called Rubisco. Rubisco plays a key role in the carbon fixation process, where it catalyzes the reaction that combines carbon dioxide and ribulose-1,5-bisphosphate to form 3-phosphoglycerate in the Calvin cycle.
What is the role of rubisco in photosynthesis?
Rubisco, ribulose bisphosphate carboxylase, is a protein molecule present in plant cells. It takes part in photosynthesis and converts inorganic CO2 into organic forms containing C-C bonds and H atoms. These are used to sustain plants in the form of sucrose (table sugar) or stored as starch
In which form is carbon dioxide primarily transported in the blood?
Carbon dioxide is primarily transported in the blood in the form of bicarbonate ions (HCO3-). This process involves the conversion of carbon dioxide to bicarbonate ions by the enzyme carbonic anhydrase in red blood cells.
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 does rubisco do?
Rubisco is an enzyme involved in carbon fixation during photosynthesis. It catalyzes the first step of the Calvin cycle, where it combines carbon dioxide and ribulose-1,5-bisphosphate (RuBP) to form two 3-phosphoglycerate molecules. This process is essential for plants to convert atmospheric carbon dioxide into organic molecules that can be used for growth and energy production.

The substance that acts as a catalyst during photosynthesis is an enzyme called Rubisco. Rubisco plays a key role in the carbon fixation process, where it catalyzes the reaction that combines carbon dioxide and ribulose-1,5-bisphosphate to form 3-phosphoglycerate in the Calvin cycle.
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.
How is carbon dioxide fixation carried out in the Calvin cycle reaction, and what is the process of CO2 fixation like?
During the Calvin cycle reaction, carbon dioxide fixation is carried out by the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). This enzyme catalyzes the reaction between carbon dioxide and ribulose-1,5-bisphosphate (RuBP) to form two molecules of 3-phosphoglycerate (3-PGA). This process is essential for plants to convert carbon dioxide into organic compounds, such as sugars, through photosynthesis.
What is the difference between rubisco and RuBP?
Ribulose bisphosphate, known as RuBP, is a 5-carbon sugar that is used in the Dark reactions (Calvin cycle) to fix carbon from CO2 (carbon dioxide). The Dark reactions begin when one molecule of CO2 is attached to RuBP. This is where RuBisCO comes in. Ribulose-1,5-bisphosphate carboxylase/oxygenase is the enzyme that catalyzes the addition of the CO2 molecule to the RuBP. This forms an unstable 6-carbon compound which immediately splits to form two molecules of a 3-carbon compound called 3-phosphoglycerate (3-PGA) Hope that is helpful!
What is the full form of RuBisCo?
Ribulose-1,5-bisphosphate carboxylase oxygenase

Name the enzyme that facilitate the transportation of carbon dioxide in the red blood cells as bicarbonate ions?
The enzyme that facilitates the transportation of carbon dioxide in red blood cells as bicarbonate ions is carbonic anhydrase. This enzyme catalyzes the reversible conversion of carbon dioxide and water to form carbonic acid, which then dissociates into bicarbonate ions and hydrogen ions.
In which form is carbon dioxide primarily transported in the blood?
Carbon dioxide is primarily transported in the blood in the form of bicarbonate ions (HCO3-). This process involves the conversion of carbon dioxide to bicarbonate ions by the enzyme carbonic anhydrase in red blood cells.
