What gas is released during photosynthesis?

Question

Luna Cruz · Accepted Answer

During photosynthesis, oxygen is produced along with glucose (not a gas)

Through a process called photosynthesis, plants convert light energy from the sun, water, and carbon dioxide from the atmosphere into glucose and oxygen. This process is sometimes referred to as a reversible reaction because the opposite of it, respiration, is also a reaction that turns glucose and oxygen into water, carbon dioxide, and energy. #"carbon dioxide " + " water " + " energy " -> " glucose " + " oxygen"# #6"CO"_2 + 6"H"_2"O" -> "C"_6"H"_12"O"_6 + 6"O"_2# Because they produce oxygen—which is necessary for life on Earth and helps maintain the ozone layer—and take in carbon dioxide, a greenhouse gas, plants play a significant role in sustaining the carbon cycle and the greenhouse effect. #" "# [Deeper Information] Where is the source of this oxygen? Oxygen is released during the light reactions of photosynthesis. Water, or #"H"_2"O"#, is split during the light reactions into gaseous oxygen, or #"O"_2#, as well as #"H"^+# protons and electrons. The electrons reduce the #"P"680^+# pigments in photosystem #"II"# once they donate their excited electrons to the primary electron acceptor. The #"H"^+# protons are let off into the stroma, and will be used later. The #"O"_2# molecules are let off as waste.
