Which step in photosynthesis does not require light?
The step in photosynthesis that does not require light is the dark reaction, also known as the Calvin cycle or the light-independent reaction. It takes place in the stroma of the chloroplasts and does not directly rely on light energy.
The step in photosynthesis that does not require light is the Calvin cycle, also known as the dark reaction or the light-independent reaction. This cycle occurs in the stroma of the chloroplasts and involves a series of chemical reactions in which carbon dioxide is converted into glucose. Unlike the light-dependent reactions that require light energy, the Calvin cycle can occur in the absence of light.
The step in photosynthesis that does not require light is called the Calvin cycle, also known as the light-independent reactions or the dark reactions. This stage takes place in the stroma of the chloroplasts and does not rely directly on light energy.
During the Calvin cycle, atmospheric carbon dioxide (CO2) is fixed and converted into glucose, a usable form of energy for plants. This process involves a series of enzyme-controlled reactions, which are fueled by the energy-rich molecules generated during the light-dependent reactions.
To determine which step in photosynthesis does not require light, you can remember that the light-dependent reactions occur in the thylakoid membranes and are responsible for capturing light energy to produce ATP and NADPH, while the Calvin cycle occurs in the stroma and uses the ATP and NADPH to convert CO2 into glucose. Therefore, the Calvin cycle is the step that does not directly rely on light.
