________ is the source of the oxygen gas released by a photosystem.
A)H₂O

C)CO₂
D)C₆H₁₂O₆

Question

Quizplus · Accepted Answer

Oxygen gas is released by the splitting of water molecules during the light-dependent reactions of photosynthesis. This process is known as photolysis, and it occurs within the thylakoid membranes of the chloroplasts. The oxygen gas is a byproduct of the reaction and is released into the atmosphere. Therefore, the correct answer is H₂O (choice A). Chlorophyll a (choice B), CO₂ (choice C), and C₆H₁₂O₆ (choice D) are involved in other steps of the photosynthesis process but are not directly responsible for the release of oxygen gas.
