How is sunlight and water are used to make ATP and oxygen in the light independent reactions?
Sunlight is not used in the dark reactions, these reactions require only the products of the light dependent reaction. When there is no sunlight, the plant goes trought the Calvin cycle, in wich it converts CO2 and other molecules into C6H12O6, the main energy source in vegetables. Knowing that the combustion formula for the glucose is: C6H12O6 + 6O2= 6CO2 + 6H2O H(variation)= (liberated), just put the formula in reverse, and you have: 6CO2 + 6H2O= C6H12O6 + 6O2 H(variation)= (absorbed) The plant uses the six mol of CO2 and six mol of water to create one mol of glucose, and six mol of oxygen, note that energy is used(absorbed) to create the glucose, but far more energy is generated by burning the glucose, so that the plant gets energy in the end of the process.

What does the light independent reactions mean?
Biochemical reactions in photosynthesis that produce organic molecules from carbon dioxide, that do not need light. This means that the aforementioned processes are 'independent of light'. N.B. Light refers to sunlight
What is the product of light independent reactions?
The product of light independent reactions are Oxygen, ATP, and NADPH. ATP is a unit of energy that the body uses; NADPH is the reduced form of NADP (as you can tell, it is missing hydrogen).
What are the 2 main reactions in photosynthesis?
Photosynthesis happens in two stages, also called reactions. The first stage is the light-dependent stage. In this stage light energy is absorbed by chlorophyll and converted into chemical energy, and water is split to produce hydrogen. The unwanted oxygen from the water is released. The second stage is the light-independent stage. In this stage the chemical energy and the hydrogen from the first stage are used to convert carbon dioxide into carbohydrates, such as glucose. More details can be found on this site by searching for photosynthesis.
What are the reactants and products of a light dependent reaction and a light independent reaction?
In photosynthesis, the reactants of the light-dependent reaction are water and light energy, which are used to produce oxygen, ATP, and NADPH. The products of the light-independent reaction (Calvin cycle) are ATP, NADPH, and carbon dioxide, which are used to produce glucose through a series of enzymatic reactions. The light-dependent reaction occurs in the thylakoid membranes of chloroplasts, while the light-independent reaction takes place in the stroma of the chloroplast.
Which molecules carry energy to the light-independent reactions?
ATP and NADPH molecules carry energy to the light-independent reactions, also known as the Calvin cycle. These molecules are produced during the light-dependent reactions of photosynthesis, where sunlight is used to generate their energy-rich forms.
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 is needed in light independent reactions?
Carbon dioxide and oxygen
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.
What are light independent and dependent reactions?
Light dependent reactions are reactions the capture light energy and convert it into chemical energy(ATP). It occur in the chloroplast of plant cells Light independent reactions are reactions capture energy and use it to produce food . It does not need sunlight
What are products of the light independent reactions?
The main purpose of the light independent reaction is to produce glucose.
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.
How do the light reactions provide for the dark reactions?
In photosynthesis, the light reactions converts the sunlight int chemical energy (ATP molecules, NADH+H). Dark reactions (light independent reactions) do not use sunlight directly, but use energy stored in ATP and NADH molecules combined with CO2 to produce sugars.
What two reactions occur in photosynthesis?
There are three carbon dioxide, water, and sunlight.
How do light reactions provide energy for dark reactions?
In photosynthesis, the light reactions converts the sunlight int chemical energy (ATP molecules, NADH+H). Dark reactions (light independent reactions) do not use sunlight directly, but use energy stored in ATP and NADH molecules combined with CO2 to produce sugars.

Biochemical reactions in photosynthesis that produce organic molecules from carbon dioxide, that do not need light. This means that the aforementioned processes are 'independent of light'. N.B. Light refers to sunlight
How are light dependent and independent reactions related?
The products of light-dependent reactions are used in light-independent reactions.
What type of reaction is 6co2 plus 6H20 - ac6h1206 plus 602?
The given reaction is a balanced chemical equation for photosynthesis. It is a combination of two separate reactions: the light-dependent reactions and the light-independent reactions. In this case, carbon dioxide and water are converted into glucose and oxygen in the presence of sunlight and chlorophyll.
