Green plants release oxygen into the atmosphere during

Question

BlackTom AI · Accepted Answer

Consider what processes in green plants release oxygen into the atmosphere.
Option 1: photosynthetic light reactions. This step of photosynthesis uses light energy to split water molecules, releasing O2 as a byproduct. It is the primary source of atmospheric oxygen on Earth, so this statement is accurate.
Option 2: fermentation. Fermentation occurs under anaerobic conditions and does not produce oxygen; it converts sugars to other substances like ethanol or lactic acid, but no O2 is released. Therefore, this is incorrect.
Option 3: glycolysis. Glycolysis breaks down glucose into pyruvate in the cytoplasm and does not involve oxygen directly. It does not release oxygen gas, so this choice is not correct in the context of O2 release.
Option 4: cellular respiration. Cellular respiration consumes oxygen to help break down glucose for energy, rather than releasing it. Thus, this option describes the use of O2, not its release, making it incorrect.
