How many PGAL are used to regenerate three molecules of RUBP?
Five PGAL (3 molecules of PGAL and 2 molecules of PGAL) are used to regenerate three molecules of RUBP during the regeneration phase of the Calvin cycle in photosynthesis.
The three carbon sugars form during the Calvin cycle are used to generate the five carbon compounds. Is it true?
No, the three-carbon sugars (Glyceraldehyde-3-phosphate) produced during the Calvin cycle are used to regenerate the five-carbon compound RuBP (ribulose-1,5-bisphosphate) in order to continue the cycle. The five-carbon compounds are not generated from the three-carbon sugars.
The six molecules of G3P formed from three turns of the Calvin cycle are converted into?
Six molecules of G3P formed from three turns of the Calvin cycle are typically used to regenerate RuBP (ribulose-1,5-bisphosphate) through a series of reactions known as the Calvin cycle regeneration phase. This process requires ATP and additional NADPH produced during the light-dependent reactions to convert G3P back into RuBP, allowing the cycle to continue.
Which molecule from the Calvin Cycle is used to replenish the five-carbon sugar RuBP which is used a the beginning of the cycles?
The molecule used to replenish RuBP in the Calvin Cycle is phosphoglycerate (PGA). PGA is converted to RuBP through a series of enzymatic reactions, allowing the cycle to continue and fix more carbon dioxide.
What are the stages of a dark reaction?
1. A five-carbon sugar molecule called ribulose bisphosphate, or RuBP, is the acceptor that binds CO2 dissolved in the stroma. This process, called CO2 fixation, is catalyzed by the enzyme RuBP carboxylase, forming an unstable six-carbon molecule. This molecule quickly breaks down to give two molecules of the three-carbon 3-phosphoglycerate (3PG), also called phosphoglyceric acid (PGA). 2. The two 3PG molecules are converted into glyceraldehyde 3-phosphate (G3P, a.k.a. phosphoglyceraldehyde, PGAL) molecules, a three-carbon sugar phosphate, by adding a high-energy phosphate group from ATP, then breaking the phosphate bond and adding hydrogen from NADH + H+. 3. Three turns of the cycle, using three molecules of CO2, produces six molecules of G3P. However, only one of the six molecules exits the cycle as an output, while the remaining five enter a complex process that regenerates more RuBP to continue the cycle. Two molecules of G3P, produced by a total of six turns of the cycle, combine to form one molecule of glucose.

A carbon atom from carbon dioxide is used to change the five carbon sugar RuBP into?
The carbon atom from carbon dioxide is used to change the five carbon sugar RuBP into two three-carbon molecules. This process is known as carbon fixation and occurs during the Calvin cycle of photosynthesis. The three-carbon molecules produced are further processed to create glucose and other organic compounds.
The Calvin cycle begins when CO2 combines with a five-carbon carbohydrate called what?
The Calvin cycle begins when CO2 combines with a five-carbon carbohydrate called ribulose-1,5-bisphosphate (RuBP) in a reaction catalyzed by the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO).
The three carbon sugars form during the Calvin cycle are used to generate the five carbon compounds. Is it true?
No, the three-carbon sugars (Glyceraldehyde-3-phosphate) produced during the Calvin cycle are used to regenerate the five-carbon compound RuBP (ribulose-1,5-bisphosphate) in order to continue the cycle. The five-carbon compounds are not generated from the three-carbon sugars.

Five carbon compound that combines with co2 in the Calvin cycle to make glicose?
The five-carbon compound that combines with CO2 in the Calvin cycle to form glucose is called ribulose-1,5-bisphosphate (RuBP). RuBP reacts with CO2 in a series of reactions facilitated by the enzyme rubisco to produce a six-carbon compound, which eventually leads to the synthesis of glucose.
What carbon atom from carbon dioxide is used to change the five-carbon sugar RuBP into what?
ATP.
What does RuBP mean?
RuBP stands for ribulose-1,5-bisphosphate. It is a five-carbon molecule involved in the Calvin cycle, a series of reactions in photosynthesis where carbon dioxide is converted into glucose. RuBP is regenerated during the cycle to ensure its continuous availability for fixing carbon dioxide.
