Why is the light dependent reactions called the light dependent reaction?
Wiki User
∙ 11y ago
it is the first stage because the product of the light dependent reaction is ATP and NADPH+H+ (Nicotinamide Adenine Dinucleotide Phosphate Hydrogen) and these are required in the light independent reaction (calvin-benson cycle)
I hope this helps :DDD

∙ 14y agoBecause they need light in the process. Also, light gives off excited electrons, which is needed to create NADPH in this process.

∙ 13y agoThis is because no light is required to power the light-independent reactions

What is produced from the splitting water during the light-dependent reactions What is this process called?
During the light dependent reaction, it produced Oxygen and Hydrogen..hope that can help...:D
Why are light dependent reactions important to the light independent reaction?
Light-dependent reactions use light to create ATP and NADPH/Reduced NADP Which is used on the Calvin cycle so of it is not present the cycle cannot continue.
What two reactions occur in photosynthesis?
There are three carbon dioxide, water, and sunlight.
What is the relationship between the light dependent reaction and Calvin cycle?
The two reactions of photosynthesis are connected by two substances: ATP and NADPH. These are produced by the light dependent reaction and are used by the light independent reaction. ATP is produced from ADP and Pi (phosphate): ADP + Pi ---> ATP This reaction requires energy to make it work, and this energy comes from light absorbed in the light dependent reaction. NADPH is produced from NADP+ and H: NADP+ + H ---> NADPH This reaction also requires energy, which is obtained from light in the light dependent reaction. The ATP and the NADPH are used in the light dependent reaction to provide energy and a source of H to convert CO2 to CH2O (carbohydrate). The products of the reactions (ADP, Pi, NADP+) are recycled in the light dependent reaction to produce more ATP and NADPH.

How does light dependent and light independent reaction work together?
The Light Reactions Provide Energy Carriers For The Dark Reactions.
What are the reactions of the first stage of the photosynthesis called?
This is called the light phase oh photosynthesis as opposed to the dark phase. During the light phase, photons excite enzymes on the thylakoid. Also can be known as Light-Dependent Reactions
Are photosynthetic pigments a part of the light dependent or light independent reactions?
The light dependent reaction, of course.
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.
What are two main reactions in photosynthesis and where do they take place?
the two stages are the light dependent variable reactions and the light dependent reactions or calvin cycle
Why are the reactions of the calvin cycle also called the light independent reaction?
The reactions of the Calvin cycle are also called the light independent reactions because they do not require light to take place. This is contrary to the light dependent process of photosynthesis.
What reaction occurs during light dependent reaction?
During light dependent reactions chlorophyll and other light-aborbing molecules capture energy from sunlight.
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 is the primary function of the light dependent reactions of photosynthesis?
Create products for which the light-independent reaction is able to use to continue the rest of photosynthesis.
What are the reactants and products of a light dependent reaction and a light independent reaction?
The reactants of light-dependent reactions in photosynthesis are H20 (water), ADP, and NADP+.The products of light-dependent pathways of photosynthesis are Oxygen, ATP, and NADPH.The reactants of light-independent reactions are ATP, NADPH, and Carbon Dioxide.The main purpose of the light independent reaction is to produce glucose.
What is produced from the splitting water during the light-dependent reactions What is this process called?
During the light dependent reaction, it produced Oxygen and Hydrogen..hope that can help...:D
What happens during light dependent reaction?
glucose is formed in the form of ATP
What are the ending products in the light dependent reaction?
The end products in light dependent reactions are: 1.Oxygen 2.ATP 3.NADPH
