Where do light independent reactions take place?
Where do light independent Calvin cycle generally occur?
This process is fueled by, and dependent on, ATP and NADPH from the light reactions. Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
In what way are the light-dependent and light-independent?
The light-independent reactions release energy, and the light-dependent reactions require energy. The light-dependent reactions produce carbon dioxide, which is then used by the light-independent reactions. The light-dependent reactions produce ATP and NADPH, which are then used by the light-independent reactions.
What happens in the light independent phase?
In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. After the energy is transferred, the energy carrier molecules return to the light-dependent reactions to obtain more energized electrons.
Do light independent reactions occur during the day?
Many students believe that the light-dependent reactions occur in the daytime and the light-independent reactions (sometimes called the “dark” reactions) occur at night when the plant can’t get sunlight, so it needs sugar. But all eukaryotes, including plants, carry out cellular respiration.
What is the meaning of light-independent reaction?
Definition. noun. The series of biochemical reactions in photosynthesis that do not require light to proceed, and ultimately produce organic molecules from carbon dioxide.
What comes out the light-dependent?
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 is the light-dependent reaction equation?
The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH. 5. The light-dependent reactions can be summarized as follows: 12 H2O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll yields 6 O2 + 12 NADPH + 18 ATP.
What is the primary purpose of the light-dependent reactions of photosynthesis?
The overall function of light-dependent reactions, the first stage of photosynthesis, is to convert solar energy into chemical energy in the form of NADPH and ATP, which are used in light-independent reactions and fuel the assembly of sugar molecules.
What is the meaning of light independent reactions?
What are some examples 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.
