It is obtained from air. Oxygen is not is not produced in dark reaction but in light reaction
Oxygen gas must be present for a combustion reaction to occur.
light-dependent reaction
This is very vague. Oxygen bubbles would be produced by some kind of chemical reaction in which one of the results is oxygen. Do you have more specifics as to when/where these oxygen bubbles would be produced?
Rusting is the reaction of iron with oxygen in the presence of water.

Oxygen gas is the gas present in air that takes part in a combustion reaction. It acts as the oxidizing agent in the reaction.
aba malay ko?

No.

nope

During the light dependent reaction, it produced Oxygen and Hydrogen..hope that can help...:D
