What gas is released during photosynthesis?

Answer 1

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.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
