The light-independent reactions are sometimes referred to as the dark reactions, though that term may be misleading as they do not actually require darkness to proceed. The term "light-independent" is used to emphasize that the reactions occur regardless of the amount of light present as long as the proper substrate compounds are available. Even this term can be criticized, however, as the availability of substrates in plants depends on photosynthesis, so the reactions cannot be said to be entirely "light-independent." Furthermore, the term "dark reactions" may be more accurate in CAM (Crassulacean acid metabolism) plants, which only take up CO2, which is necessary for the reactions to proceed, at night.

Where is the second stage of photosynthesis occur?
The second step of photosynthesis happens between the chloroplasts, rather than inside of them. This particular step is also independent of light, so if the light suddenly goes away for some reason, it doesn't totally stop the photosynthesis all at once.
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 part of photosynthesis where energy from the light reactions is used to make simple sugars?
The Calvin cycle, which is the second stage of photosynthesis, is where energy from the light reactions is used to convert carbon dioxide into simple sugars like glucose through a series of enzymatic reactions. This process occurs in the stroma of the chloroplast and requires ATP and NADPH produced during the light reactions.
During which stage of photosynthesis does carbon fixation take place?
Carbon fixation takes place during the Calvin cycle, which is the second stage of photosynthesis. In this process, carbon dioxide from the atmosphere is converted into organic compounds by using the energy obtained from light-dependent reactions.
What occurs in the second phase of photosynthesis?
In the second phase of photosynthesis, known as the light-independent reactions or the Calvin cycle, carbon dioxide is converted into glucose using the energy stored from the light-dependent reactions. This process takes place in the stroma of the chloroplasts and does not require light to occur.
Which reaction during photosynthesis is light-independent?
That is the second step. It is called dark cycle
What is the Calvin cyle?
It is the second step of photosynthesis. It does not need light
Which term is the part of photosynthesis when energy is used to make sugar glucose?
Light-independent reactions
Where is the second stage of photosynthesis occur?
The second step of photosynthesis happens between the chloroplasts, rather than inside of them. This particular step is also independent of light, so if the light suddenly goes away for some reason, it doesn't totally stop the photosynthesis all at once.
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 is the name for the first and second stage of photosynthesis?
1st-Light reaction 2nd-Dark reaction
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.
Where does photosythsis occur?
Photosynthesis occurs in the choloroplast, a organelle in the cell. More specifically: photosynthesis is divided into several steps. The first step/steps is the light reaction, or light-independent reaction. This happens to absorb the photons, and with it, the energy, from the sun. This part occurs in the thylakoid membranes of the chloroplast. The second part is the Calvin cycle, or the dark/ light-dependent reaction. This part takes the results of the first reaction, and change that energy that was captured into glucose. This occurs in the grana of the choloroplast.
What is produced in the second phase of photosynthesis?
The second phase of photosynthesis is called the light-independent reactions, also known as the Calvin cycle. In this phase, the products of the light-dependent reactions, ATP and NADPH, are used to convert carbon dioxide into glucose. So, the main product of the second phase of photosynthesis is glucose.
What is light reaction and dark reaction?
Photosynthesis can be divided into two part: light reaction is the first stage of photosynthesis, occurring only in the presence of light, during which energy captured from light drives the production of ATP. dark reaction is the second stage of photosynthesis, not requiring light to occur, and during which energy released from ATP drives the production of organic molecules from carbon dioxide.
What are the two basic steps to photosynthesis?
The Light Dependent process and then the Light Independent process (known as the Calvin Cycle).
What is stored in phase 1 of photosynthesis?
There are two products. Those are NADPH and ATP.
