What does the light independent stage of radioactive tracers mean?
Wiki User
∙ 13y ago
The light-independent stage of photosynthesis, also known as the Calvin cycle, is where carbon dioxide is converted into glucose using the energy collected during the light-dependent stage. Radioactive tracers can be used to track the movement of carbon atoms through this process by marking them with a radioactive isotope like carbon-14. This helps scientists understand the flow of carbon and the rates of different biochemical reactions in the Calvin cycle.

What happens in the 'dark reaction' of photosynthesis?
The dark reaction, also known as the Calvin cycle, involves the conversion of carbon dioxide into glucose using ATP and NADPH generated during the light-dependent reactions. This process takes place in the stroma of the chloroplast and does not require direct sunlight, hence the name "dark reaction." The Calvin cycle is essential for the production of sugars that can be used as an energy source by the plant.
Where does the light indepentent stage of photosynthesis occurs?
The light-independent stage of photosynthesis, also known as the Calvin cycle, occurs in the stroma of the chloroplasts. Here, carbon dioxide is fixed and converted into sugars using the ATP and NADPH generated during the light-dependent stage.
What are the light independent and dependent stages of photosynthesis?
The light-dependent stage of photosynthesis occurs in the thylakoid membranes of chloroplasts, where light energy is absorbed to produce ATP and NADPH. In the light-independent stage (Calvin cycle), these products are used to convert carbon dioxide into glucose in the stroma of the chloroplasts.
Why is the first stage called the light dependent reaction?
The first stage is called the light-dependent reaction because it relies on light energy to drive the process of photosynthesis. During this stage, light is absorbed by chlorophyll in the chloroplasts, which initiates a series of reactions that produce ATP and NADPH for the Calvin cycle.
Where is the second stage of photosynethsis?
The second part of photosynthesis is called the light independent. it does not require light for it can also be refair to as the dark phase. The first part of photosynthesis is called the light dependent for its requires light.
2 stages of photosynthesis?
The 2 stages are light-dependent stage and the light-independent stage. In the light-dependent stage, photolysis of water 12H20 --------> 6O2 + 24H Light energy is converted to Chemical energy In the light-independent stage, enzyme controlled reaction 6CO2 + 24H -----------------> C6H12O6 + 6H20
What is dark face of photosynthesis?
The dark phase of photosynthesis, also known as the Calvin cycle, is the stage where carbon dioxide is fixed and converted into glucose. This step does not require light and takes place in the stroma of the chloroplast. The dark phase is essential for the production of sugar molecules that provide energy for the plant's growth and development.
What products of the light reaction are used in the light independent stage of photosynthesis?
NADPH and ATP
What are the two stage of photosyntesis?
A series of light-dependent reactions that are temperature independent, and a series of temperature-dependent reactions that are light independent.
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 does photosynthises mean?
Photosynthesis is when plants, algae, cyanobacteria, etc. create energy with the aid of light. The presence of light is what instigates photosynthesis to occur since the "Light-dependent" stage is the first stage. Then there is the "light-independent" stage, which I believe is the calvin-benson cycle.

What are the two main stages for photosynthesis?
The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin Cycle). In the light-dependent reactions, light energy is used to split water molecules and produce ATP and NADPH. In the Calvin Cycle, ATP and NADPH are used to convert carbon dioxide into glucose.
Name two stages of photosynthesis?
There is the light-dependent stage, where sunlight interacts with choloropyll to set up an electron-transport chain, then there is the chemical stage, where glucose molecules are synthesized from CO2 and H2O.
What does the light independent reactions mean?
The light-independent reactions, also known as the Calvin cycle, are the second stage of photosynthesis where carbon dioxide is converted into glucose using the energy produced during the light-dependent reactions. This process occurs in the stroma of the chloroplast and does not directly require light to proceed, hence the name "light-independent reactions."
