Guida verificata passo dopo passo1
Understand that the Calvin cycle is part of photosynthesis, which occurs in the chloroplasts of plant cells.
Recognize that the Calvin cycle itself does not directly require light; it is known as the light-independent reactions or dark reactions.
Identify that the Calvin cycle requires ATP and NADPH, which are produced during the light-dependent reactions of photosynthesis.
Explain that during the light-dependent reactions, light energy is captured by chlorophyll and used to convert ADP and NADP+ into ATP and NADPH, respectively.
Conclude that while the Calvin cycle does not use light directly, it depends on the products of the light-dependent reactions (ATP and NADPH) to drive the fixation of carbon dioxide into glucose.
