How many molecules of ATP are produced in photosynthesis?
Glucose combines with oxygen (oxidation), forming carbon dioxide, water and 38 molecules of ATP.
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.
Is ATP produced in light reactions?
The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH.
What are the 3 molecules produced in the light reaction?
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. The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration.
How many ATP are produced in light independent reactions?
The light-independent reactions can be summarized as follows: 12 NADPH + 18 ATP + 6 CO2 yields C6H12O6 (glucose) + 12 NADP+ + 18 ADP + 18 Pi + 6 H2O.
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 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 non cyclic Photophosphorylation?
1 ATP
Non-cyclic photophosphorylation produces 1 ATP and 2 NADPH2 molecules.
What is produced in the light-independent reactions of photosynthesis?
The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH….
| Goal | Convert light energy into chemical energy |
|---|---|
| Location | Chloroplasts—thylakoids |
| Input | Sunlight, H2O, NADP+, ADP |
| Output | NADPH, ATP, O2 |
How many ATP are produced in the light reaction?
How many ATP are produced in light reaction? The net result of this reaction is the production of 2 ATP and 9 NADPH and the photolysis of water. The ATP and NADPH will be used in the Calvin-Benson-Bassham cycle of the dark reactions.
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 ATPs does it take to make one glucose molecule?
Producing one glyceraldehyde-3-phosphate requires 6 NADPH and 9 ATP (12 electrons, 24 photons). Producing one glucose requires 12 NADPH and 18 ATP (24 electrons, 48 photons). How many ATPs are required for the synthesis of a glucose molecule in dark reactions?
What is the role of light in photosynthesis?
The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP. Similarly, is ATP produced in photosystem 1 or 2?
