Where does light independent reaction take place?
stroma
The light-independent reactions of photosynthesis take place within the stroma. It contains enzymes that work with ATP and NADPH to “fix” carbon from carbon dioxide into molecules that can be used to build glucose.
Where does light independent reaction take place in the chloroplast?
3.1 Light-independent reactions of photosynthesis. The light-independent reactions represent the known Calvin–Benson–Bassham (CBB) cycle which takes place in the stroma of chloroplasts and is the primary pathway of carbon fixation of C3 plants [119].
What goes in and out of light-independent reactions?
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 the process of light independent reaction?
The light independent process (also called dark reactions or the Calvin-Benson cycle) takes place in the stroma of the chloroplast. Carbon dioxide is modified by series of chemical reactions to form carbohydrates. The energy for these reactions comes from ATP and NADPH generated during the light dependent process.
What is the difference between light-dependent and light independent reaction?
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.
What is another name for the light independent reaction?
the Calvin cycle
Other names for light-independent reactions include the Calvin cycle, the Calvin-Benson cycle, and dark reactions.
What is the difference between light-dependent and light-independent reaction?
What is the difference between light dependent and light independent reaction?
What are three differences between light-dependent and light-independent reactions of photosynthesis?
The light-dependent reac-tions require light and water, occur in the thylakoids, and produce ATP and NADPH. The light-independent reactions require carbon dioxide, occur in the stroma, and produce high-energy sugars. What are the three primary factors that affect the rate of photosynthesis?
What are the light independent reactions in photosynthesis?
Using the energy carriers formed in the first steps of photosynthesis, the light-independent reactions, or the Calvin cycle, take in CO 2 from the environment. An enzyme, RuBisCO, catalyzes a reaction with CO 2 and another molecule, RuBP. After three cycles, a three-carbon molecule of G3P leaves the cycle to become part of a carbohydrate molecule.
Where do the light dependent reactions take place?
Figure 1 The light-dependent reactions harness energy from the sun to produce ATP and NADPH. These energy-carrying molecules travel into the stroma where the Calvin cycle reactions take place.
How are light independent reactions organized in the Calvin cycle?
Figure 1. Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place. The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration.
How are light independent reactions initiated in the stroma?
In the stroma, in addition to CO2, two other components are present to initiate the light-independent reactions: an enzyme called ribulose bisphosphate carboxylase (RuBisCO), and three molecules of ribulose bisphosphate (RuBP), as shown in Figure 2. RuBP has five atoms of carbon, flanked by two phosphates.
