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 is needed by the Calvin Cycle?
The Calvin cycle is a 'light independent cycle' that takes place in the chloroplasts. In this cycle, water and carbon dioxide is converted into organic compounds. The key enzyme involved is Rubisco.
Are the reactions that fix carbon dioxide sometimes called dark reactions?
Yes, the reactions that fix carbon dioxide are sometimes called dark reactions because they do not directly require light energy to occur. These reactions typically take place in the stroma of chloroplasts during photosynthesis and are also known as the Calvin cycle.
Does photophosphorylation require Carbon Dioxide?
No, photophosphorylation is a light-dependent process that occurs in the thylakoid membranes of chloroplasts during photosynthesis. It does not directly involve the use of carbon dioxide. Carbon dioxide is involved in the light-independent Calvin cycle, which uses the products of the light-dependent reactions (ATP and NADPH) to fix carbon dioxide and produce carbohydrates.
What is the difference between the light dependent and the dark reactions of the Calvin cycle?
The light-dependent reactions of the Calvin cycle require light to occur and take place in the thylakoid membranes of the chloroplast. These reactions generate ATP and NADPH. In contrast, the dark reactions (Calvin-Benson cycle) occur in the stroma of the chloroplast and use ATP and NADPH from the light-dependent reactions to fix carbon dioxide and produce sugars.

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.
Is photolysis in the Calvin cycle?
No, photolysis does not occur in the Calvin cycle. Photolysis is the process of breaking down water molecules in the light-dependent reactions of photosynthesis to produce oxygen, while the Calvin cycle is the series of reactions that occur in the stroma of the chloroplast to fix carbon dioxide and produce sugars.
Why is the Calvin benson cycle sometimes called the carbon fixation cycle?
Photosynthesis starts out using the energy from sunlight to get things started, but it ends with the dark reactions, which don't need sunshine to complete sugar production. In the Calvin cycle, ATP and NADPH from the light reactions are used to produce sugars.
Which of the following reactions ensures that the Calvin cycle can make a continuous supply of glucose?
The regeneration of RuBP (ribulose-1,5-bisphosphate) ensures that the Calvin cycle can make a continuous supply of glucose. This regeneration step allows the cycle to repeatedly fix carbon dioxide and synthesize glucose molecules.

What are PGAL and RuBP?
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.
The light reactions occur in the while the Calvin cycle occurs in the?
The light reactions occur in the thylakoid membranes of the chloroplasts, while the Calvin cycle (dark reactions) occurs in the stroma of the chloroplasts. The light reactions capture light energy and convert it into chemical energy (ATP and NADPH), which is used in the Calvin cycle to fix carbon dioxide and produce sugars.
What is the name of the molecule that carries electrons from the light dependent reactions to the Calvin cycle?
The molecule that carries electrons from the light-dependent reactions to the Calvin cycle is called NADPH (nicotinamide adenine dinucleotide phosphate). NADPH is produced during the light-dependent reactions in photosynthesis and then used in the Calvin cycle to help fix carbon dioxide into sugars.
What is a C3 and C4 or CAM organisms?
C3, C4, and CAM are different photosynthetic pathways used by plants to fix carbon dioxide. C3 plants, such as wheat and rice, use the Calvin cycle to fix carbon dioxide. C4 plants, like corn and sugarcane, use a different enzyme to fix carbon dioxide and are more efficient in hot and dry conditions. CAM plants, such as cacti and pineapple, open their stomata at night and fix carbon dioxide into organic acids to use during the day.
