The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. The Calvin cycle reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. The Calvin cycle reactions use chemical energy from NADPH and ATP that were produced in the light reactionslight reactionsThe light reactions, also known as photolysis reactions, convert energy from the sun into chemical energy in the form of NADPH and ATP. These reactions must take place in the light and in chloroplasts of plants.https://chem.libretexts.org › The_Light_Reactions
What are the end products of the light dependent reactions that need the presence of light to occur?
The light-dependent reaction is a photochemical reaction taking place in the thylakoid membranes of chloroplasts, where light energy is transformed into adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate (NADPH).
What is the product of the Calvin cycle quizlet?
The product of the Calvin cycle is a triose-phosphate sugar that is either exported from the chloroplast or used to regenerate RUBP.
What is the main product of carbon reactions?
The simplified version of this chemical reaction is to utilize carbon dioxide molecules from the air and water molecules and the energy from the sun to produce a simple sugar such as glucose and oxygen molecules as a by product.
What is the result of the Calvin cycle?
In Summary: The Calvin Cycle The resulting six-carbon compound is broken down into two three-carbon compounds, and the energy in ATP and NADPH is used to convert these molecules into G3P. Photosynthesis forms a balanced energy cycle with the process of cellular respiration.
What is produced in the Calvin cycle of photosynthesis quizlet?
In the Calvin cycle, carbon dioxide is incorporated into organic compounds, a process called carbon fixation. The Calvin cycle produces a compound called G3P. Most G3P molecules are converted into RuBP to keep the Calvin Cycle operating.
What are the products of photosynthesis?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product.
What are the reactants and end products of the light reactions?
During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).
What is the first stable product of Calvin cycle?
The 3 carbon compound, that is, 3 phosphoglyceric acid (PGA), is the first stable compound formed in the Calvin cycle.
Is water produced in the Calvin cycle?
Further, since the Calvin cycle involves 3 reactions of CO2 with RuBP, you get a net production of 3 molecules of water.
What are the 3 inputs of photosynthesis?
In photosynthesis, water, carbon dioxide, and energy in the form of sunlight are inputs, and the outputs are glucose and oxygen.
Why does Calvin cycle need products of light?
Because it is needed to convert oxygen into sugar. Because it is needed to convert sugar into oxygen.
What happens after the Calvin cycle?
The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.
What are the products of the Calvin cycle?
Products. The immediate products of one turn of the Calvin cycle are 2 glyceraldehyde-3-phosphate (G3P) molecules, 3 ADP, and 2 NADP+. (ADP and NADP+ are not really “products”. They are regenerated and later used again in the Light-dependent reactions).
What is the primary product of the Calvin cycle?
The primary product of the Calvin cycle is glyceraldehyde three phosphate or G3P.
What are the products of the light reactions?
Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place.
Which compound is produced during regeneration PGA?
Carbon dioxide enters the cycle and is fixed by Rubisco to a 5-carbon sugar called ribulose biphosphate (RuBP), which is immediately broken down to form two 3-carbon molecules of phosphoglycerate (PGA).
What is the final product of Phase Stage 1 of the Calvin cycle?
Figure 5.15 The Calvin cycle has three stages. In stage 1, the enzyme RuBisCO incorporates carbon dioxide into an organic molecule. In stage 2, the organic molecule is reduced. In stage 3, RuBP, the molecule that starts the cycle, is regenerated so that the cycle can continue.
Which products of the Calvin cycle are used in the light reactions?
What two products of the light reactions are used up in the calvin cycle? NADPH, which is an electron carrier and can be reused, and ATP, or ADP, which is an energy molecule that can be rebuilt in another light reaction.
What are the inputs and products of the Calvin cycle?
1. For each of the two main stages of photosynthesis, identify the inputs. Inputs of the light reactions are light and water, and ADP, P, and NADP+ from the Calvin cycle. Inputs of the Calvin cycle are CO2, and ATP and NADPH from the light reactions.
What are the 3 products of light dependent reactions?
Glucose, ATP and O2.
Why does it take three turns of the Calvin cycle to produce G3P the initial product of photosynthesis?
Why does it take three turns of the Calvin cycle to produce G3P, the initial product of photosynthesis? Because G3P has three carbon atoms, and each turn of the cycle takes in one carbon atom in the form of carbon dioxide.
What are the products glycolysis?
Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy. Instead, glycolysis is their sole source of ATP.
What is the final product of the light independent reactions?
The light-independent reactions (Calvin cycle) use stored chemical energy from the light-dependent reactions to “fix” CO2 and create a product that can be converted into glucose. The ultimate goal of the light-independent reactions (or Calvin cycle) is to assemble a molecule of glucose.
What happens to co2 in the Calvin cycle quizlet?
What happens to carbon dioxide molecules in the Calvin cycle reactions? carbon dioxide molecules are bonded together with the electrons and H’s from NADPH to form glucose.
What is the main final product of the Calvin cycle how many turns of the Calvin cycle are needed to produce this product?
Summary of Calvin cycle reactants and products Three turns of the Calvin cycle are needed to make one G3P molecule that can exit the cycle and go towards making glucose.
What are the end products of the Calvin cycle quizlet?
The end product of the Calvin Cycle is a 3-C GP3 molecule and two 3-C G3P molecules must combine to create one 6-C glucose which is two spins around the Calvin Cycle.
Is ATP a product of the Calvin cycle?
ATP and NADPH produced by the light reactions are used in the Calvin cycle to reduce carbon dioxide to sugar. ATP is the energy source, while NADPH is the reducing agent that adds high-energy electrons to form sugar. • The Calvin cycle actually produces a three-carbon sugar glyceraldehyde 3-phosphate (G3P).
