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.

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 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.

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

The final product of the Calvin cycle is glucose. It takes six turns to reach a glucose molecule. What is the Calvin cycle? The second stage of photosynthesis in which carbon atoms from carbon dioxide are combined using the energy in ATP and NADPH to make glucose.

How many ATP are required for one turn of the Calvin cycle?

18 ATP

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

How many water molecules are produced in the reduction phase of the Calvin cycle?

Six water molecules

Water is a product of the reduction phase of the Calvin cycle. a. How many water molecules are produced? Six water molecules are formed.

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 produced in 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. … This cycle releases ATP and NAPH.

Which molecules are produced during the Calvin cycle?

The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.

How many ATP molecules are required for every CO2 molecule entering Calvin cycle?

3 molecules

Hence for every CO2 molecule entering the Calvin cycle 3 molecules of ATP and 2 of NADPH are required.

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.

Why does the Calvin cycle have to turn 6 times?

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). The remaining G3P molecules regenerate RuBP which enables the system to prepare for the carbon-fixation step.

What are the 4 steps of the Calvin cycle?

The Calvin cycle has four main steps: carbon fixation reduction phase carbohydrate formation and regeneration phase. Energy to fuel chemical reactions in this sugar-generating process is provided by ATP and NADPH chemical compounds which contain the energy plants have captured from sunlight.

Which of the following is are required in 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.

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).

Why does it take three turns of the Calvin cycle to produce G3P quizlet?

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 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.

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 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 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.

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.

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.
