PGAL is more commonly know as G3P, or glyceraldehyde-3-phosphate. It is the final product of the Calvin Cycle, or the dark reaction in plants. Two G3P molecules, which are each 3-carbon compounds, go on to create glucose. RuBP is ribulose bis phosphate . It is an organic compound used in Calvin cycle, it is used to fix CO2 during Calvin cycle . where one CO2 molecule is covalently bonded to RuBP to form an unstable intermediary compound that later breaks down by an enzymatic reactions to form G3P. It is vital for carbon fixation in plants.

How many carbons does PGAL have?
PGAL - Phosphoglyceraldehyde is the breakdown of one molecules of glucose and became two PGAL with 3 carbon atoms and 1 phosphate each pgal has. Added By John Estapon
Why is PGAL considered a versatile molecule?
Igit
What happens when RuBP reacts with O2?
According to Biologists, the process in which oxygen becomes attached to RuBp which is fixed is known as photorespiration. This process does not apply to carbon dioxide.
How many RuBP are needed to make one glucose molecule?
6
What is the intermediate product of glycolysis that can be used in the biosynthesis of lipids?
The intermediate products of glycolysis include glucose-6-phosphate, fructose-6-phosphate, fructose-1 6-bisphosphate, PGAL, bisphosphoglycerate, and PEP. The main intermediate products are fructose-1 6-bisphosphate, PGAL, and PEP.
What is the biological significance of PGAL?
Calvin Cycle shown in link. PGAL - 1.Used to produce sugars etc.. 2.Used to regenerate the 5 carbon acceptor of CO2 (RuBP).
Which molecule from the Calvin Cycle is used to replenish the five-carbon sugar RuBP which is used a the beginning of the cycles?
PGAL
How many PGAL are used to regenerate three molecules of RUBP?
One molecule of PGAL has 3 carbons in it (therefore three turns are necessary). Six molecules would therefore require 18 turns of the Calvin Cycle.
What is produced from the Calvin cycle?
Amino acid, lipids, and carbon hydrate(glucose).
What is the function of G3P in photosynthesis?
In the Calvin Cycle [CC], carbon dioxide combines with RuBP which creates PGA. From the light dependent reactions in photosynthesis which occurs in the thylakoid, ATP and NADPH are produced. Those two products combine with the PGA to from PGAL. one of the 6 molcules of PGAL combine with a phosphate is used by the plants to create sugars, starch, etc. PGAL rearranges with 5-carbon phosphate and another phosphate is given to PGAL from the ATP light-dependent reaction product producing RuBP again. This restarts the cycle starting with carbon dioxide combining with the RuBP.
PGAL is synthesized during?
Pgal is synthesized during the calvin cycle
How many carbons does PGAL have?
PGAL - Phosphoglyceraldehyde is the breakdown of one molecules of glucose and became two PGAL with 3 carbon atoms and 1 phosphate each pgal has. Added By John Estapon
Where does PGAL appear in cellular respiration?
PGAL is found in glycolisis.It is a mid product.
What are most of the PGAL made in the Calvin cycle are used for?
PGAL is a major product of the Calvin Cycle. PGAL is produced and can be used in the light reactions, where they synthesize additional molecules of ATP and NADPH.
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.
Which more contain more energy three molecules of carbon dioxide or one molecule of phosphoglyceraldehyde pgal?
PGAL
How many pgal molecules can there be during the Calvin cycle?
There can be up to 12 PGAL molecules during the Calvin cycle
