How many molecules of carbon dioxide are used up by the plant in producing each molecule of oxygen?

Answer 1

At least six

this is because photosynthesis uses Carbon Dioxide, Water and Sunlight, to produce glucose. A glucose molecule is made of 6 carbon, 6 oxygen, and 12 hydrogen atoms. Since carbon dioxide is the only molecule in photosynthesis containing carbon atoms, and it only contains one per molecule, you would need a minimum of six molecules of it combined with six molecules of water in order to produce glucose. (with an extra 12 oxygen atoms)

Answer 2

The Chemical equation for Photosynthesis is: 6 CO2 + 6 H2O → C6H12O6 + 6 O2

However, this equation can be misleading, especially in the case of your question. The answer to the question : How many water molecules and how many carbon dioxide molecules are need for Respiration is not 6 and 6. It is important to think of chemical equations not as a definite concrete structure, but more as a recipe that can be modified. All this equation tells us is that the Chloroplasts in plant cells require six molecules of Carbon Dioxide and six molecules of Water to create (using light energy to drive the reaction) a molecule of glucose and six molecules of oxygen. However, this equation is simplified, like a fraction. The actual number of molecules that are processed by photosynthesis even per second is extremely large. For example, a plant may use 6 million Carbon dioxide molecules and 6 million Water molecules to produces 1 million Glucose molecules and 6 million Oxygen molecules. Essentially, the formula is a ratio. You can do whatever with the numbers (of molecules, not the actual molecular formula) as long as you do the same with the numbers on the right, as you would do with any other formula, for example in Mathematics. As a conclusion, the number of Water and Carbon dioxide molecules required for photosynthesis is a variable, but the basic formula for Photosynthesis is: 6 CO2 + 6 H2O → C6H12O6 + 6 O2

Answer 3

Six molecules of carbon dioxide needed for photosynthesis of glucose:

6 CO2 + 6 H2O --> C6H12O6

Answer 4

For every 1 molecule of carbon dioxide used, 1 molecule of oxygen is also produced.
