Ribulose-1,5-bisphosphate carboxylase oxygenase

2 answers


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.

RuBisCo

(Ribulose bisphosphate carboxylase)

1 answer


Ribose is a 5-carbon sugar molecule commonly found in RNA, while ribulose is also a 5-carbon sugar molecule, but it plays a key role in the Calvin cycle of photosynthesis as a starting molecule for carbon fixation. Ribose is involved in the formation of RNA molecules, whereas ribulose is a key part of the process of converting carbon dioxide into organic compounds in plants.

Ribulose bisphosphate carboxylase, also known as RuBisCO, is a key enzyme involved in photosynthesis. It catalyzes the first major step of carbon fixation by combining carbon dioxide with ribulose-1,5-bisphosphate to produce 3-phosphoglycerate. RuBisCO is considered one of the most abundant proteins on Earth due to its crucial role in converting atmospheric carbon into energy for plants.

dust. because when it reaches water, it starts to shrink and die

1 answer


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!

ATP is required in the Calvin-Benson cycle for the initial step of carbon fixation, where carbon dioxide is combined with ribulose-1,5-bisphosphate (RuBP) by the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). This reaction produces an unstable intermediate compound that is quickly converted into two molecules of 3-phosphoglycerate.

2 answers


The last step of the Calvin cycle is regeneration of RuBP (Ribulose-1,5-bisphosphate) using ATP to continue the cycle. This is necessary to replenish the RuBP molecules that are used in the initial carbon fixation step.
