- During oxygenic photosynthesis, what happens to the oxygen atoms that were originally present only in substrate water molecules (as they are transformed into product molecules)? they end up in carbon dioxide, glucose, and water molecules they end up in both glucose and water molecules they end up in glucose molecules only they end up in carbon dioxide molecules only they end up in diatomic oxygen gas molecules onlyarrow_forwardWhich of the following statements incorrectly describes the structure of a chloroplast? A chloroplast has both an outer membrane and an inner membrane, often separated by a narrow intermembrane space. The inner membrane of the chloroplast encloses the stoma, a dense fluid filled with enzymes needed for photosynthesis. A chloroplast contains thylakoids, which are flat, saclike structures suspended in the stroma. Thylakoids of a chloroplast are arranged into stacks called grana.arrow_forwardDuring what part of photosynthesis is a water molecule split?
