How many carbon dioxide molecules are needed to make a single glucose molecule answers com?
1 Answer. Ernest Z. Flavio P. You need 6 molecules of CO2 .
How many molecules are needed to form a glucose molecule?
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 CO2start text, C, O, end text, start subscript, 2, end subscript, 18 ATP, and 12 NADPH, to produce one molecule of glucose.
How many carbon dioxide and water molecules do you need to make 1 glucose molecule and 6 oxygen molecules?
Reactants of Photosynthesis Notice that it takes six molecules of water and six molecules of carbon dioxide to make one molecule of glucose. The inputs and outputs of photosynthesis are shown in the diagram at right.
How much CO2 is produced from glucose?
When one molecule of glucose is completely oxidised, 38 ATP and 4 CO2 are produced.
Why are six carbon molecules required?
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.
How much carbon dioxide is needed for photosynthesis?
Below the threshold no assimilation takes place. Thus it seems that only about two-thirds of the atmospheric carbon dioxide is available for photosynthesis”.
How many oxygen molecules are required for glycolysis?
Glycolysis requires no oxygen. It is an anaerobic type of respiration performed by all cells, including anaerobic cells that are killed by oxygen. For these reasons, glycolysis is believed to be one of the first types of cell respiration and a very ancient process, billions of years old.
How many molecules of carbon dioxide are needed for photosynthesis?
6 molecules Overall equation for photosynthesis 6 molecules of carbon dioxide are required, one for each carbon atom in glucose. 6 molecules of oxygen are produced as a by product of water oxidation.
How many CO2 molecules are produced in glycolysis?
During the glycolysis process of two pyruvic acid molecules one molecule of carbon dioxide is produced.
How much CO2 is produced in glycolysis?
Answer and Explanation: Glycolysis produces zero molecules of carbon dioxide.
Why are six carbon dioxide molecules CO2 are required to make one glucose molecule C6H12O6?
Why are six carbon dioxide molecules required to make one glucose molecule? 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.
How many molecules of CO2 are fixed during each turn of the Calvin cycle?
Each turn of the cycle involves only one RuBP and one carbon dioxide and forms two molecules of 3-PGA.
How much carbon dioxide does a plant need?
For most crops the saturation point will be reached at about 1,000–1,300 ppm under ideal circumstances. A lower level (800–1,000 ppm) is recommended for raising seedlings (tomatoes, cucumbers and peppers) as well as for lettuce production.
Why are 12 molecules of water used in photosynthesis?
Two molecules of water split to form1 molecule of oxygen and the respective number of electrons and hydrogen ions are also formed . Now for producing 12 molecules of NADPH , total 12 molecules of water are required.
How many CO2 molecules are needed for oxidation of glucose in glycolysis?
Six molecules of CO2 are required to synthesise one molecule of glucoses each of which undergoes a C3 cycle.
How many molecules of glucose are in photosynthesis?
So, we see that six molecules of carbon dioxide produce one molecule of glucose, and that's the ratio between those two products and reactants.
How many molecules of glucose are products in the photosynthesis equation?
In photosynthesis, energy from light is used to convert carbon dioxide and water into glucose and oxygen. For 6 carbon dioxide and 6 water molecules, 1 glucose molecule and 6 oxygen molecules are produced.
How many co2 are produced per glucose?
Total 4 CO2 molecules are released in the TCA cycle per glucose molecule, i.e. in the two rounds of the cycle.
How many carbon dioxide molecules are produced in cellular respiration?
Three carbon dioxide molecules are produced during the cellular respiration if we start with one molecule of pyruvate. The first is made when pyruvate is converted to acetyl-CoA (intermediate step/pyruvate dehydrogenase). The second is produced when D-isocitrate is converted to alpha-ketoglutarate.
How much co2 does glucose produce?
Decarboxylation: Carbon atoms are removed from the organic molecule (glucose) to form carbon dioxide. Aerobic respiration involves the complete combustion of glucose (6C) – so six CO2 molecules are produced.
How many carbon dioxide molecules are needed to produce a glucose during photosynthesis quizlet?
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. Describe the relationship between the light and the Calvin cycle.
How is CO2 made into glucose?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
How does Calvin cycle convert CO2 to glucose?
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.
How many turns of the Calvin cycle would be required for a plant to make one molecule of glucose?
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. Thus, the correct answer is option C.
Is carbon dioxide required for photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons.
Why are 12 molecules of water as substrate used in the equation c6 h12 o6?
–Two molecules of water split to form1 molecule of oxygen and the respective number of electrons and hydrogen ions are also formed . –Now for producing 12 molecules of NADPH , total 12 molecules of water are required.
How many water molecules are involved in photosynthetic equation?
6 water water molecules Overall equation for photosynthesis 6 water water molecules are oxidized, and become the source of electrons for carbon dioxide reduction. 6 molecules of carbon dioxide are required, one for each carbon atom in glucose. 6 molecules of oxygen are produced as a by product of water oxidation.
How many CO2 are produced per glucose?
Total 4 CO2 molecules are released in the TCA cycle per glucose molecule, i.e. in the two rounds of the cycle.
