Where do the 12 hydrogen atoms in a molecule of glucose produced during photosynthesis come from?
It takes six atoms of carbon (C) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6). These atoms come from carbon dioxide (CO2) and water (H2O).
How many turns of the Calvin cycle are required to make a glucose?
six turns
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 glucose molecules are produced in photosynthesis?
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.
Where do the 6 atoms of carbon in glucose come from?
The carbon atoms in glucose come from the atmospheric carbon dioxide molecules that are taken in by plants for photosynthesis.
What is the glucose molecule?
glucose, also called dextrose, one of a group of carbohydrates known as simple sugars (monosaccharides). Glucose (from Greek glykys; “sweet”) has the molecular formula C6H12O6. It is found in fruits and honey and is the major free sugar circulating in the blood of higher animals. Dextrose is the molecule d-glucose.
Why does it take 6 turns of the Calvin cycle to make glucose?
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 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. 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 hydrogen atoms are in photosynthesis?
12 hydrogen atoms
Chemically speaking, the inputs to photosynthesis are six carbon atoms, 12 hydrogen atoms and 18 oxygen atoms. Glucose uses six carbon, 12 hydrogen, and six oxygen molecules.
How many molecules of glucose can you get from 6 CO2 and 6 water molecules?
one glucose molecule
Explanation. In words, the equation may be stated as: Six carbon dioxide molecules and six water molecules react to produce one glucose molecule and six oxygen molecules. The reaction requires energy in the form of light to overcome the activation energy needed for the reaction to proceed.
Where does the hydrogen in glucose come from?
Where do the hydrogen and oxygen atoms come from that become part of the glucose molecule made during photosynthesis? The oxygen molecules come from carbon dioxide and water. The hydrogen atoms come from water.
Where do carbon atoms in glucose come from quizlet?
Terms in this set (8) Where do carbon atoms in glucose come from? Carbon dioxide and water combine to form a glucose, water, and oxygen. What is required for that process to occur?
