In plants, the process of photosynthesis produces glucose (C₆H₁₂O₆)and oxygen from carbon dioxide and water. Which of the following statements about photosynthesis is true?

Question

Quizplus · Accepted Answer

During photosynthesis, carbon dioxide molecules are broken down and their carbon atoms are used to form glucose. Therefore, all of the carbon atoms from the carbon dioxide molecules are found in glucose. Additionally, oxygen is released as a byproduct of photosynthesis, but more atoms are not present at the beginning than at the end, as the same atoms are rearranged during the process. More carbon dioxide is absorbed than released by the plant during photosynthesis. Water is not synthesized by the plant from H₂ and O₂, but rather split into hydrogen and oxygen molecules during the light reactions of photosynthesis.
