light reaction or sunlight
The light reaction makes two substances needed by the dark reaction: ATP and NAPH. As long as these two substances are available the dark reaction can continue, even in the absence of light. However when they run out more light is needed to replace them.
Carbon dioxide and oxygen
ATP and NADH2
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.
Because energy rich compounds needed in dark reaction are produced during light reactions.
sunlight
what raw matirials is needed in light reaction
An essential condition for the reaction of bromine with ethane is the presence of UV light. UV light provides the energy needed to break the bromine molecule and initiate the reaction with ethane, forming bromoethane.
The materials needed in the light reaction phase of photosynthesis include sunlight, water, and chlorophyll. These components are used to convert light energy into chemical energy in the form of ATP and NADPH. Oxygen is also produced as a byproduct of this phase.
