The fixation of carbon from carbon dioxide.
Some substitutes for rubisco include enolase, PEP carboxylase, and phosphoenolpyruvate (PEP) carboxykinase. These enzymes can have higher affinities for carbon dioxide, reducing the rate of photorespiration in plants.
The initial molecule that binds with carbon dioxide in the Calvin cycle is ribulose-1,5-bisphosphate (RuBP). This reaction is catalyzed by the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO).
Carbon dioxide acts as a source of carbon, it is an inorganic molecule which reactions with RuBP (Ribulose 1,5 bisphosphate) to for an unstable 6 carbon compound which breaks down into 2 molecules of GP (Glycerate 3-phosphate). Note: The reaction of CO2 and RuBP is catalysed by Rubisco (Ribulose 1,5 bisphosphate carboxylase oxygenase) GP in turn is used to synthesize amino acids (with the use of nitrates from the soil) and fatty acids.
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.
Rubisco, short for ribulose-1,5-bisphosphate carboxylase/oxygenase, does not end with "ase" because it is an enzyme that catalyzes a specific reaction involving ribulose bisphosphate, rather than being named solely for its enzymatic function. The "ase" suffix is commonly used for enzymes, but in the case of rubisco, the name reflects both the substrate it acts upon and its dual function in carboxylation and oxygenation processes. This unique naming convention highlights its importance in photosynthesis and its complex role in carbon fixation.
Delta G (d)
Yes, the only difference is that a catalyst is used to change the activation energy of the reaction, so the reaction will occur at a different rate.
Yes, the product increases because positive catalysts increase the rate of the reaction.
Some substitutes for rubisco include enolase, PEP carboxylase, and phosphoenolpyruvate (PEP) carboxykinase. These enzymes can have higher affinities for carbon dioxide, reducing the rate of photorespiration in plants.
Rubisco is an important enzyme

Oxidation of carbon monoxide to carbon dioxide. Reduction of nitrogen monoxide back to nitrogen. Oxidation of hydrocarbons to water and carbon dioxide.
The reaction between iodine and acetone is catalyzed by hydroxide ions present in the reaction mixture. The hydroxide ions help in the deprotonation of acetone, making it more reactive towards iodine. This catalysis increases the rate of reaction and allows for the formation of iodoform.
