What is the role of rubp in photosynthesis?
RuBP is ribulose biphosphate. It's purpose is in the dark reaction. It is formed by taking a phosphate, coming from the splitting of ATP, and joining it with RuP, changing RuP (ribulose phospate) into RuBP. RuBP is then able to join with CO2 and form an unstable 6C molecule which is the basis for the dark reaction.
When carbon dioxide combines with RuBP what happens?
RuBP and CO2 form 2 molecules of G3P (glyserate 3 phosphate) in calvin cycle with aid from the enzyme rubisco.
In phosphorylation is ATP utilized to regenerate RuBP?
During the carbon reduction cycle in plants during phosphorylation, ATP is used to break down RuBP and form glucose and other sugars however ATP is Not used while the cycle is regenerating RuBP.
What will happen to the concentration of RuBP and GP if the supply of carbon dioxide is reduced?
GP will be reduced as there will be less carbon dioxide to break down RuBP to form 2 shorter chain molecules.
How does RuBP get regenerated?
In the Calvin Cycle 3 ATP molecules are required to regenerate RUBP from 5 G3P. RuBP is an addition of CO2 that is involved with carbon fixation.
Does different enzyme controls photosynthesis?
RuBP There mmight be more but rubp is the enzyme used in the Calvin cycle
Does the Calvin cycle require RuBP?
yes it does, the RuBP starts the Calvin Cycle.... it begins there
What three substances are introduced into the Calvin benson cycle to produce to sugar molecules?
The Calvin Benson cycle uses ATP (adenosine triphosphate), NADPH (Nicotinamide adenine dinucleotide phosphate), and CO2 (carbon dioxide) to create glucose.
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!
How is food prepared in Plants during Photosynthesis?
Light independent stage. During Calvin cycle, RuBP used with Co2 to form glycerate-3-phosphate which can be used to form sugar(food).
What compound is produced during regeneration?
RuBP
What is the meaning of rubp in biology?
Ribulose Bisphosphate
