six turns

It takes six turns to produce one glucose molecule in the Calvin cycle.

How many turns of the Calvin cycle are required to make a sucrose?

Because the carbohydrate molecule has six carbon atoms it takes six turns of the Calvin cycle to make one carbohydrate molecule (one for each carbon dioxide molecule fixed).

How many turns of the Calvin cycle are required to produce one molecule of glucose assume one CO2 is fixed in each turn of the cycle?

23. The carbohydrate produced directly from the Calvin cycle is not glucose but the three-carbon compound glyceraldehyde 3-phosphate (G3P). Each turn of the Calvin cycle fixes one molecule of CO2 therefore it will take 3 turns of the Calvin cycle to net one G3P.

How many cycles of the Calvin cycle does it take to produce one G3P molecule how many cycles of the Calvin cycle does it take to produce one G3P molecule?

3 cycles

Every 3 cycles of the Calvin Cycle (light independent reaction) 6 molecules of G3P are produced only 1 is used to produce glucose.

What is the main final product of the Calvin cycle how many turns of the Calvin cycle are needed to produce this product 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.

How many turns does the Calvin cycle take?

Three turns of the Calvin cycle are needed to make one G3P molecule that can exit the cycle and go towards making glucose.

How many Calvin cycles are involved in the synthesis of one glucose molecule by photosynthesis?

There are 6 atoms of carbon required for the synthesis of one glucose molecule. Hence to produce one molecule of hexose sugar six turns of Calvin cycle are required.

What are the 4 steps of the Calvin cycle in order?

The Calvin cycle has four main steps: carbon fixation reduction phase carbohydrate formation and regeneration phase.

What are the 3 stages of Calvin cycle?

The Calvin cycle is organized into three basic stages: fixation reduction and regeneration.

What is end product of Calvin cycle?

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.

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.

How many CO2 molecules are in one turn of the Calvin cycle?

a. How many CO molecules are used in one turn of the Calvin cycle? Three CO molecules are used each time.

What is the number of turns of Calvin cycle to generate one molecule of hexose sugar?

As calvin cycle takes only one carbon (as CO2) at a time. So it takes six turns of the cycle to produce a net gain of one hexose or glucose.

What is required for the Calvin cycle?

The Calvin Cycle

All three necessary conditions are required – chlorophyll pigments the chloroplast “theater ” and enzyme catalysts. The first stage transforms light energy into chemical energy stored to this point in molecules of ATP and NADPH.

What happens to CO2 in the Calvin cycle?

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. … cO2 goes in and O2 comes out. it helps to exchange them using simple diffusion.

What happens in Phase 1 of the Calvin cycle?

During the first phase of the Calvin cycle carbon fixation occurs. The carbon dioxide is combined with ribulose 1 5-bisphosphate to form two 3-phosphoglycerate molecules (3-PG). … RuBisCO is the first enzyme utilized in the process of carbon fixation and its enzymatic activity is highly regulated.

What is the net result of Calvin cycle?

Each turn of the Calvin cycle “fixes” one molecule of carbon that can be used to make sugar. It takes three turns of the Calvin cycle to create one molecule of glyceraldehyde-3 phosphate. After six turns of the Calvin cycle two molecules of glyceraldehyde-3 phosphate can be combined to make a glucose molecule.

Why are 6 CO2 molecules needed in photosynthesis?

Six carbon dioxide molecules (CO2) are required to create one glucose molecule (C6H12O6) because carbon dioxide has one carbon per molecule while glucose molecules have six carbons. … The Calvin cycle which takes place in the stroma uses ATP and NADPH to convert carbon dioxide to sugar.

How does the Calvin cycle make glucose?

Six “turns” of the Calvin cycle use chemical energy from ATP to combine six carbon atoms from six CO2 molecules with 12 “hot hydrogens” from NADPH. The result is one molecule of glucose C6H12O6.

How many molecules of glucose are produced by each cycle of the light reaction?

The Chemical Reaction

The overall chemical reaction for photosynthesis is 6 molecules of carbon dioxide (CO2) and 6 molecules of water (H2O) with the addition of solar energy. This produces 1 molecule of glucose (C6H12O6) and 6 molecules of oxygen (O2).

How many ATP molecules are produced in the Calvin cycle?

18 ATP

The Calvin cycle uses 18 ATP and 12 NADPH molecules to produce one glucose molecule.

What transfers the electrons generated during the light cycle to CO2 during the Calvin cycle?

-light energy is absorbed by the chlorophyll molecules to drive the transfer of electrons and H+ from water to the electron acceptor NADP+ reducing it to NADPH. -NADPH produced by the light reactions provides the electrons for reducing carbon in the calvin cycle.

Where does the Calvin cycle occur quizlet?

Where does the Calvin Cycle occur? The Calvin Cycle occurs in the stroma whereas the light reactions occur in the thylakoids.

What are the stages of Calvin cycle quizlet?

What are the three phases or steps of the Calvin Cycle? Fixation reduction and regeneration.

What happens during the Calvin cycle quizlet?

In the Calvin cycle carbon dioxide is incorporated into organic compounds a process called carbon fixation. … In the light reactions energy is absorbed from sunlight and converted into a chemical energy in the Calvin cycle carbon dioxide and chemical energy are used to form organic compounds.

How does the Calvin cycle produce high energy sugars?

The Calvin cycle uses carbon dioxide molecules as well as ATP and NADPH from the light-dependent reactions to make sugars. The reactions of the Calvin cycle use ATP and NADPH as energy sources. They do not directly require light.

How many G3P are produced in the Calvin cycle?

6 molecules

Explanation: Every 3 cycles of the Calvin Cycle (light independent reaction) 6 molecules of G3P are produced only 1 is used to produce glucose.

What chemicals are used in the Calvin cycle to make glucose?

In the Calvin cycle carbon atoms from CO2​start text C O end text start subscript 2 end subscript are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by and dependent on ATP and NADPH from the light reactions.

What occurs during 2nd half of glycolysis?

The second half of glycolysis extracts ATP and high-energy electrons from hydrogen atoms and attaches them to NAD+. Two ATP molecules are invested in the first half and four ATP molecules are formed by substrate phosphorylation during the second half.

Does Calvin cycle require light?

The Calvin cycle refers to the light-independent reactions in photosynthesis that take place in three key steps. Although the Calvin Cycle is not directly dependent on light it is indirectly dependent on light since the necessary energy carriers ( ATP and NADPH) are products of light-dependent reactions.

How many carbon atoms would a molecule have which after accepting CO2?

3 carbons

How many carbon atoms would a molecule have which after accepting (fixing) CO2 would have 3 carbons (of PGA)? The studies very unexpectedly showed that the accepter molecule was a 5-carbon ketose sugar – it was ribulose bisphosphate (RuBP).

How many carbon atoms would a molecule have which after accepting CO2 would have 3 carbon of PGA?

We now have a total of eighteen carbons in the cycle (three from CO2 and fifteen from the three molecules of RuBP). As the three RuBP molecules accept a molecule of carbon dioxide they immediately break down into six 3-carbon molecules of phosphoglyceric acid (PGA).
