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
What else can I help you with?
Does different enzyme controls photosynthesis?
During photosynthesis, the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) plays a key role in the fixation of carbon dioxide. This enzyme helps catalyze the initial steps of the Calvin cycle, which is essential for converting carbon dioxide into glucose. Without RuBisCO, photosynthesis would not occur efficiently.
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 protein is produced during photosynthesis?
The protein produced during photosynthesis is called RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase), which plays a key role in fixing carbon dioxide from the atmosphere into organic molecules within the chloroplasts of plant cells.
What molecule can bind to rubisco and inhibit carbon fixation rates?
The molecule that can bind to RuBisCO and inhibit carbon fixation rates is oxygen. This process is known as photorespiration, and occurs when RuBisCO binds with oxygen instead of carbon dioxide, leading to a decrease in the efficiency of photosynthesis.
How many carbon are there in RuBP?
Ribulose bisphosphate (RuBP) contains five carbon atoms. It plays a crucial role in the Calvin cycle of photosynthesis, where it acts as a substrate for the enzyme RuBisCO, facilitating the fixation of carbon dioxide.
Who discovered rubisco?
Rubisco was discovered by the American scientist, Martin Kamen, in the 1940s. Rubisco is the most abundant enzyme on Earth and plays a crucial role in the process of photosynthesis by fixing carbon dioxide into sugars.
Does different enzyme controls photosynthesis?
During photosynthesis, the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) plays a key role in the fixation of carbon dioxide. This enzyme helps catalyze the initial steps of the Calvin cycle, which is essential for converting carbon dioxide into glucose. Without RuBisCO, photosynthesis would not occur efficiently.
What is the most abundant protein in the biosphere?
Rubisco is considered the most abundant protein in the biosphere. It is an enzyme involved in photosynthesis, found in plants, algae, and some bacteria. Rubisco plays a crucial role in fixing carbon dioxide from the atmosphere into organic molecules.
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 protein is produced during photosynthesis?
The protein produced during photosynthesis is called RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase), which plays a key role in fixing carbon dioxide from the atmosphere into organic molecules within the chloroplasts of plant cells.
What enzyme plays a major role in Calvin cycle?
Rubisco
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)
What is the full form of RuBisCo?
Ribulose-1,5-bisphosphate carboxylase oxygenase
The major enzyme that catalyzes the reduction of carbon dioxide is called?
The major enzyme that catalyzes the reduction of carbon dioxide is called ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). RuBisCO is a key enzyme involved in the process of photosynthesis in plants and algae.
What molecule can bind to rubisco and inhibit carbon fixation rates?
The molecule that can bind to RuBisCO and inhibit carbon fixation rates is oxygen. This process is known as photorespiration, and occurs when RuBisCO binds with oxygen instead of carbon dioxide, leading to a decrease in the efficiency of photosynthesis.
Carbon fixation is catalyzed by what enzyme?
Carbon fixation is catalyzed by the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). RuBisCO is found in plants, algae, and some bacteria, and plays a key role in the Calvin cycle, where it converts carbon dioxide into organic molecules like glucose.
What would happen in a chloroplast containing an unusual form of rubisco that did not bind oxygen?
Photosynthesis would occur but photorespiration would not.
