There is a light reaction and a dark reaction (the Calvin Cycle). The light reaction is divided into 3 parts, Photosystem II, the Electron Transport Chain, and Photosystem I. The light reaction begins in Photosystem II when light hits the thylakoid so the chlorophyll loses and electron, and the electron moves up in energy levels and reaches the primary anceptor. From here it passes through the electron transport chain which is similar to the electron transport chain in cellular respiration, but it occurs in the thykaloids proton gradient is reversed through the membrane. Then it enters phtosystem I which is essentially the same thing as photosystem I, and the electrons from there pass through another electron transport chain. This produces ATP and NADPH which are used in the dark reaction, or Calvin Cycle, which is again similar to the Citric Acid Cycle but it begins with Acetyl acetate and produces 2 ATP 6 NADH and 1 FADH 2 per every 2 turns which are required to produce one glucose molecule, the ultimate goal of photosynthesis.
I hope this was enough detail.

∙ 14y ago2 different reactions:
1. light dependent reaction (light reaction)
- requires the use of light
2. light independent reaction (dark reaction/calvin-benson cycle)
- does not require the use of light

∙ 9y agoI would take it as what happen after photosynthesise. Give out oxygen and make food. I not sure I am correct. But do view other relevant answers, there are 3 , some would say.

Light reaction always need light.It takes place only at day time. Dark reaction does not need lightWiki User
∙ 14y ago- Light-dependent stage where sunlight needs to stimulate electrons
- Light-independent stage (also called Calvin Cycle) where the final products of photosynthesis is made.

[it's just a guess but I'm 100% sure of it... :))]

What are the two molecules that fuel dark reactions?
ATP and NADPH fuel the dark reactions of photosynthesis.
What are two phrases in photosynthesis?
There are two steps. Light dependent and light independant reactions
What is the two sets of reactions that need to occur in order for photosynthesis to take pace?
light dependent and light independent reactions
What are two types of organisms that can undergo photosynthesis?
producers
What are stages of photosynthesis?
Photosynthesis consists of two stages: a series of light-dependent reactions that are temperature independent and a series of temperature-dependent reactions that are light independent. The rate of the first series, called the light reaction, can be increased by increasing light intensity (within certain limits) but not by increasing temperature. In the second series, called the dark reaction, the rate can be increased by increasing temperature (within certain limits) but not by increasing light intensity.
What two types of reactions occur during photosynthesis?
The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.
What powers the ATP synthase enzyme in the light-dependent reactions of photosynthesis?
Photosynthesis is the process that plants convert solar energy into the energy stored in chemical bonds. This consists of two reactions, light dependent and light independent.
The two major sets of reactions involved in photosynthesis are?
Light Reactions and the Calvin Cycle Reactions.
Are the reactions of photosynthesis?
There are two reactions. Those are light dependent and independent.
What are two stages in the process of of photosynthesis?
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.
The two major sets of rections involved in photosynthesis?
light reactions and Calvin cycle reactions
What are the two molecules that fuel dark reactions?
ATP and NADPH fuel the dark reactions of photosynthesis.
What are the stage in the process of photosynthesis?
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.
What two processes have to occur for photosynthesis to take place?
divide into parts: light reactions and dark reactions
What are two phrases in photosynthesis?
There are two steps. Light dependent and light independant reactions
What are the two reactions used in photosynthesis?
There are three carbon dioxide, water, and sunlight.
What are the two stages in photosynthesis?
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.
