The carbon in water is recycled during photosynthesis.
The carbon in carbon dioxide is recycled during photosynthesis.
The correct answer is: The carbon in carbon dioxide is recycled during photosynthesis.
During photosynthesis, plants take in carbon dioxide (CO2) from the atmosphere through tiny pores called stomata in their leaves. Inside the plant's cells, carbon dioxide is combined with water (H2O) in a process known as carbon fixation. This reaction is catalyzed by an enzyme called Rubisco.
The carbon from carbon dioxide is then incorporated into a molecule called glucose (C6H12O6) through a series of chemical reactions. Glucose is a carbohydrate that serves as a source of energy for plants.
The process of photosynthesis also releases oxygen as a byproduct. The oxygen molecules (O2) that are produced are released back into the atmosphere through the stomata.
Overall, photosynthesis allows plants to convert carbon dioxide into glucose, effectively recycling the carbon and using it to build organic molecules.
The correct response is: The carbon in carbon dioxide is recycled during photosynthesis.
u sure?
Yes, I am sure. During photosynthesis, plants take in carbon dioxide (CO2) and use it to synthesize glucose molecules. The carbon from CO2 is incorporated into glucose and other organic compounds, effectively recycling the carbon.
