How many ATP does it take to make glucose in photosynthesis?

A G3P molecule contains three fixed carbon atoms, so it takes two G3Ps to build a six-carbon glucose molecule. It would take six turns of the cycle, or 6 CO2​start text, C, O, end text, start subscript, 2, end subscript, 18 ATP, and 12 NADPH, to produce one molecule of glucose.

How ATP is produced in photosynthesis?

They require light, and their net effect is to convert water molecules into oxygen, while producing ATP molecules—from ADP and Pi—and NADPH molecules—via reduction of NADP+. ATP and NADPH are produced on the stroma side of the thylakoid membrane, where they can be used by the Calvin cycle.

How much energy is used in photosynthesis?

The part of the solar spectrum used by plants has an estimated mean wavelength of 570 nm; therefore, the energy of light used during photosynthesis is approximately 28,600/570, or 50 kcal per einstein.

How much ATP is produced in the light reactions of photosynthesis?

The light-dependent reactions can be summarized as follows: 12 H2O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll yields 6 O2 + 12 NADPH + 18 ATP.

How is ATP made in the chloroplast?

The chloroplast adenosine triphosphate (ATP) synthase is located in the thylakoid membrane and synthesizes ATP from adenosine diphosphate and inorganic phosphate at the expense of the electrochemical proton gradient formed by light-dependent electron flow.

How is ATP used in plants?

ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules.

What is ATP in photosynthesis full form?

Adenosine triphosphate (ATP) is an organic compound and hydrotrope that provides energy to drive many processes in living cells, such as muscle contraction, nerve impulse propagation, condensate dissolution, and chemical synthesis.

Which form of energy is used in photosynthesis?

In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose.

What organelle does photosynthesis occur in?

chloroplasts
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

How many net ATP molecules are produced during the light reactions of photosynthesis for each molecule of hexose synthesized?

How many net ATP molecules are produced during the light reactions of photosynthesis for each molecule of hexose synthesized? Thus, three molecules of ATP and two molecules of NADPH are consumed in incorporating a single CO2 molecule into a hexose such as glucose or fructose.

How many ATP are produced in Calvin cycle?

In summary, it takes six turns of the Calvin cycle to fix six carbon atoms from CO2. These six turns require energy input from 12 ATP molecules and 12 NADPH molecules in the reduction step and 6 ATP molecules in the regeneration step.

How many ATP are produced in chloroplast?

Chloroplast photosystems generate ATP and NADPH during photosynthesis. To fix one CO2 molecule, three ATP molecules and two NADPH molecules (ATP/NADPH = 1.5) are consumed by the Calvin-Benson-Bassham (CBB) cycle (Fig.

How many ATP are used in photosynthesis?

During photosynthesis 18 molecules of ATP are used in c3 plants. Out of these 12 are used in synthesis of 1 glucose molecule and 6 for regeneration of RUBP. Click to see full answer. Besides, how ATP is produced in photosynthesis?

How many ATP are there in the light independent cycle?

Each turn of the light independent cycle (calvin-benson) requires 1 CO2, 3 ATP, and 2 NADPH. It needs 6 turns of the cycle to make 1 molecule of glucose because glucose has a 6 carbon atom backbone. Aerobic respiration needs 2 ATP to start reactions and when completed will have a net yield of 36 ATP.

How many ATP are required for the formation of one glucose molecule?

In C3 plants for fixation of one carbon dioxide molecule 3 ATP are needed where as in the case of c4 plants for fixation of one carbon dioxide molecule 5 ATP are needed. According to photo synthesis reaction 6 carbon dioxide molecules are needed for the formation one glucose molecule.

How many ATP are there in 1 turn of C3 cycle?

That depends on the type of plant. In C3 plants, 12 NADPH and 18 ATP are used to make 1 molecule of glucose. Since the C3 cycle has to take place 6 times to make 1 glucose molecule, hence 1 turn of C3 cycle uses 3 ATP molecules and 2 NADPH molecules.
