Light pollution sometimes. But most time it produces the light that emits in a better way.
Light reaction is not produced by chlorophyll .
Light reaction or Hill's reaction.
no
Chemical reactions can produce heat and energy but not all chemical reactions produce them. Exothermic reactions produce heat and energy (possibly in the form of photons/light), while endothermic reaction absorb them.
To produce Sugar or Carbhydrates.
They are used to produce sugar during the dark reaction
Light Reaction
Combustion
Yes, the also use ATP and luciferase which catalyzes this oxidation reaction. This reaction produces light and 100% of the energy produced by this reaction is released as light.
an exothermic combination reaction
oxygen
The two combine to produce smoke.
