How are the dark reactions that occur in plants dependent on the light reactions?
The dark reactions that occur in plants are dependent on the light reactions because the dark reactions need ATP and NADPH. ATP and NADPH are energy molecules that dark reactions need to do their job.
The light reactions of photosynthesis convert what energy to what energy?
During photosynthesis plants transform light energy from the sun to chemical energy.
Compare and contrast light dependent and light independent reactions of photosynthesis.?
Light dependent reactions : The first stage of the photosynthetic system is the light-dependent reaction, which converts solar energy into chemical energy. The light dependent reaction produces oxygen gas and converts ADP and NADP+ into the energy carriers ATP and NADPH. In plants, light dependent reactions occur in the thylakoid membranes of the chloroplasts and use light energy to synthesize ATP and NADPH. The light dependent reaction has two forms; cyclic and non-cyclic reaction. In the non-cyclic reaction, the photons are captured in the light-harvesting antenna complexes of photosystem II by chlorophyll and other accessory pigments.The cyclic reaction takes place only at photosystem I. Once the electron is displaced from the photosystem, the electron is passed down the electron acceptor molecules and returns back to photosystem I, from where it was emitted; hence the name cyclic reaction. Light-independent reaction : In photosynthesis, the light-independent reactions, also somewhat misleadingly called the dark reactions (they don't require darkness, but they do require the products of the light reactions), are chemical reactions that convert carbon dioxide and other compounds into glucose. It occurs in the stroma, the fluid filled area of a chloroplast outside of the thylakoid membranes. These reactions, unlike the light-dependent reactions, do not need light to occur; hence the term dark reactions. These reactions take the products of the light-dependent reactions and perform further chemical processes on them. There are two light-independent reactions: carbon fixation and the Calvin-Benson cycle.
What occurs during the first stage of photosynthesis?
The first stage of photosynthesis is the light dependent reactions. During this stage, photons excite the electrons that move through Photosystem I, Photosystem II, and the Electron Transport Chain to produce ATP and NADPH. The ATP and NADPH produced in this first step are then used later during the Calvin Cycle.
What happens during each of the two stages of photosynthesis?
These stages are called the light reactions and the dark reactions. The light reactions take place in the presence of of light. The dark reactions do not require direct light, however dark reactions in most plants occur during the day.
What are the reactions in which light energy from the sun is converted to chemical energy called?
light-dependent reactions. such as photosynthesis in green plants.
How are the dark reactions that occur in plants dependent on the light-reactions?
The dark reactions that occur in plants are dependent on the light reactions because the dark reactions need ATP and NADPH. ATP and NADPH are energy molecules that dark reactions need to do their job.

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.
Plants make their own food using energy that comes from the what?
Plants make their own food using energy that comes from the sun. Plants trap energy from the sun with the help of chlorophyll. Their food is prepared during two reactions,i.e; light dependent reaction & light independent reaction which take place simultaneously.
What do plants get their food from?
Plants do not make food at night because food (glucose) production is dependent upon light. Photosynthesis is powered by sunlights energy producing NADPH, and ATP. These molecules are essential for the production of glucose in the calvin cycle. Therefore without the light dependent reactions, the light independent reactions associated with photosynthesis cannot take place.
What is the primary purpose of the light-dependent portion of the energy synthesis pathway in plants?
The primary purpose of the light dependent portion of photosynthesis is to convert light energy into chemical energy stored in ATP and NADPH, which will then be used in the light independent reactions.
In what form is the energy that is produced by the light dependent reactions of photosynthesis?
In our point of view we feel the light energy as heat. However plants use this to make sugar and live off of it.
During photosynthesis plants generate sugars which contain chemical potential energy but plants need external energy to perform photosynthesis. Where does this external energy come from?
nuclear reactions in the Sun
What organisms convert energy from the sun into chemical energy?
Photosynthesis is the cellular process that converts solar energy into chemical energy.
What is the point of light reactions?
To produce energy for plants during the day time. ( courtesy Blackman high school )
The light reactions of photosynthesis convert what energy to what energy?
During photosynthesis plants transform light energy from the sun to chemical energy.
