In the Calvin-Benson cycle, the molecule that donates phosphate is ribulose bisphosphate (RuBP). This five-carbon sugar phosphate reacts with carbon dioxide in the presence of the enzyme ribulose bisphosphate carboxylase/oxygenase (RuBisCO) to form 3-phosphoglycerate (3-PGA). Additionally, ATP provides the energy and phosphate groups needed for the conversion of 3-PGA into glyceraldehyde-3-phosphate (G3P) during the cycle. Thus, ATP and RuBP are key contributors to the donation of phosphate in this process.

What happens during the CalvinBenson cycle or dark reaction?
the final product of the calvin benson cycle used to produce glucose is?
Will lithium and phosphate form an ionic bond?
Yes, lithium and phosphate can form an ionic bond. Lithium, a metal, can donate its electron to phosphate, a non-metal, leading to the formation of an ionic compound.
What does NADPH add to the Calvin benson cycle?
NADPH is used in the Calvin-Benson cycle to provide reducing power needed for the synthesis of carbohydrates. It helps to reduce 3-phosphoglycerate into glyceraldehyde-3-phosphate, a key intermediate in the cycle. This reduction reaction is catalyzed by the enzyme glyceraldehyde-3-phosphate dehydrogenase.
What compound is regenerated in the urea cycle?
The compound regenerated in the urea cycle is ornithine. This compound allows the cycle to continue by combining with carbamoyl phosphate to form citrulline, which is then further processed to produce urea.
How is the Calvin cycle completed?
The Calvin cycle is completed when the cycle of chemical reactions converts carbon dioxide into glucose. This process requires the input of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate), which provide the energy needed to drive the reactions. The final step of the Calvin cycle regenerates the molecule needed to start the cycle again.
In the Calvin-Benson cycle which can donate phosphate?
In the Calvin-Benson cycle, ATP can donate a phosphate group to regenerate ribulose-1,5-bisphosphate (RuBP) in the regeneration phase of the cycle. This process is vital for the continuation of carbon fixation and the production of carbohydrates.
What happens during the CalvinBenson cycle or dark reaction?
the final product of the calvin benson cycle used to produce glucose is?
Is dihydrogen phosphate acid or base?
The dihydrogen phosphate ion - (H2PO4)-is an anion.
Will lithium and phosphate form an ionic bond?
Yes, lithium and phosphate can form an ionic bond. Lithium, a metal, can donate its electron to phosphate, a non-metal, leading to the formation of an ionic compound.
What is ATP cycle?
Work consumes ATP, which is then regenerated from ADP and phosphate.
What is the driving force behind the carbon oxygen cycle and the phosphate cycle?
The driving force behind the carbon oxygen cycle is photosynthesis, where plants convert carbon dioxide and sunlight into energy, releasing oxygen as a byproduct. In the phosphate cycle, the main driving force is the weathering of rocks that contain phosphate minerals, which releases phosphorus into the soil for uptake by plants and subsequent cycling through the ecosystem.
What is the role of ATP in synthesis?
ATP is used in the Calvin cycle in it's phosphorylation role; transferring phosphate groups to Calvin cycle intermediates that then go through the conformational rearrangements which result in the sugar product, glyceraldehyde-3-phosphate that leaves the cycle and the reconstitution of oxaloacete, beginning the cycle again.
What results from three turns of the Calvin cycle?
glyceraldehyde-3-phosphate (G3P)
Which of the following is not a possible fate of glucose-6-phosphate?
It can enter into the urea cycle
What is produce during the Calvin Cycle?
glyceraldehyde-3-phosphate (G3P) and water
How the equivalent weight of calcium phosphate be calculated?
The equivalent weight of calcium phosphate is calculated by dividing the molar mass of calcium phosphate by the valency factor of the phosphate ion. Since calcium phosphate is a salt with the formula Ca₃(PO₄)₂, its molar mass is calculated by adding the molar masses of calcium and phosphorus (since there are three calcium ions and two phosphate ions in the formula). The valency factor of phosphate ion is 2 since it can donate or accept 2 electrons.
What does NADPH add to the Calvin benson cycle?
NADPH is used in the Calvin-Benson cycle to provide reducing power needed for the synthesis of carbohydrates. It helps to reduce 3-phosphoglycerate into glyceraldehyde-3-phosphate, a key intermediate in the cycle. This reduction reaction is catalyzed by the enzyme glyceraldehyde-3-phosphate dehydrogenase.
