photosynthesis begins when pigments in photosystem i absorb light.
it breaks down ATP.
it breaks down ATP.
True. An exothermic reaction releases energy in the form of heat, light, and sometimes electricity. This energy is typically given off to the surroundings, resulting in a rise in temperature.
True. The burning of wood involves the oxidation of wood (losing electrons) by oxygen in the air, resulting in the release of energy in the form of heat and light. This is a classic example of an oxidation-reduction (redox) reaction.
photosynthesis begins when pigments in photosystem i absorb light.
The light reaction produces ATP and NADPH, which are needed to fuel the dark reaction. The dark reaction (Calvin Cycle) uses the ATP and NADPH produced in the light reaction to fuel the conversion of carbon dioxide into glucose. In essence, the light reaction provides the energy source that drives the dark reaction.
Though the reaction is not triggered by light, it does need the products produced in the "light-dependent " process.
why light reaction of photosynthesis is essential before the dark reaction can procced?
A.T.P. and N.A.D.H are formed during light reaction.
There must be a light reaction first before dark reaction. This is so that there is something to be compared.
the respiriration is such a oxidative reductive process ... and during plant it have two complex more process consist of seriese of steps DARK reaction and Light reaction.................... dark reaction need no light wheather in day time or night time...................... some how the light reaction are done in the prescence of light ..........during the light reaction the formation of the light reaction is just one ATP Which is responsible for the production of dark reaction .............
chemical reaction brought on by light ( latin: photo - light)
