What is needed for light independent reactions?
After the energy from the sun is converted and packaged into ATP and NADPH, the cell has the fuel needed to build carbohydrate molecules. These energy-carrying molecules travel into the stroma where the Calvin cycle reactions take place. …
What is an example of light independent reactions?
Explanation: The light independent reactions are also called the Calvin cycle. This is the process in which carbon dioxide is used to produce glucose. The light independent reactions require the ATP and NADPH produced by the light reactions.
What are the raw materials of light-independent reactions?
In photosynthesis, water, carbon dioxide, ATP, and NADPH are reactants. RuBP and oxygen are products. In photosynthesis, water and carbon dioxide are reactants. GA3P and oxygen are products.
What is the difference between light-dependent and light-independent reactions in photosynthesis?
In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.
How are light dependent and independent reactions linked?
The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH. The light-independent reactions use the ATP and NADPH from the light-dependent reactions to reduce carbon dioxide and convert the energy to the chemical bond energy in carbohydrates such as glucose.
What is required for both the light dependent and light independent reactions to proceed?
Light dependent reactions occur in Grana of Chloroplasts, Light Independent reactions occur in Stroma of Chloroplasts. Hence Chloroplasts are required for both the light-dependent and light-independent reactions to proceed. Elaine C. The answer is energy.
In what way are the light dependent and light independent reactions?
The light-dependent reactions of photosynthesis use water and produce oxygen. The light-independent reactions release energy, and the light-dependent reactions require energy. The light-dependent reactions pass electrons through an electron transport chain to the light-independent reactions.
Which best describes light independent reactions?
Which best describes light-independent reactions? They are the first stage of photosynthesis. They utilize the energy stored in ATP and NADPH. They create energy-rich ATP and NADPH.
What are the three main steps of light reactions?
The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration.
Where are light-dependent reactions?
The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.
What are the 2 types of photosynthesis?
There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. The general principles of anoxygenic and oxygenic photosynthesis are very similar, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.
Which is the best type of photosynthesis?
C3 photosynthesis is the typical photosynthesis that most plants use and that everyone learns about in school (it was all we knew about until a few decades ago). C4 and CAM photosynthesis are both adaptations to arid conditions because they result in better water use efficiency.
What parts of photosynthesis are light dependent?
The Two Parts of Photosynthesis Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.
What are the two main stages of photosynthesis and where do they occur?
Most autotrophs make food using photosynthesis. This process occurs in two stages: the light reactions and the Calvin cycle. Both stages of photosynthesis take place in chloroplasts. The light reactions take place in the thylakoid membranes, and the Calvin cycle takes place in the stroma.
