Question

which number remains unchanged during photosynthesis? (1 point) the number of water molecules the number of glucose molecules the number of carbon atoms the number of carbon dioxide molecules

Explanation:

Photosynthesis follows the law of conservation of mass, which states that atoms are neither created nor destroyed in a chemical reaction. In photosynthesis, the reaction is \(6CO_2 + 6H_2O \xrightarrow[\text{Chlorophyll}]{\text{Light}} C_6H_{12}O_6 + 6O_2\). The number of water molecules, glucose molecules, and carbon dioxide molecules changes as reactants are converted to products. However, the number of carbon atoms remains the same because the carbon atoms from carbon dioxide are used to form glucose, and their total count is conserved.

Answer:

the number of carbon atoms
