The light-independent reactions of photosynthesis are also known as the Calvin cycle.
The light-independent reactions of photosynthesis are also known as the Calvin cycle. To arrive at this answer, you can approach it by understanding the process of photosynthesis and the terminology associated with it.
Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight into chemical energy stored in glucose. It occurs in two main stages: the light-dependent reactions and the light-independent reactions.
The light-dependent reactions take place in the thylakoid membrane of the chloroplasts and rely on light energy to produce ATP and NADPH, which are energy carriers. These reactions involve the absorption of light by chlorophyll and the splitting of water molecules, resulting in the release of oxygen.
On the other hand, the light-independent reactions occur in the stroma of the chloroplasts, where ATP and NADPH generated in the light-dependent reactions are utilized. These reactions do not directly require light energy but are dependent on the products of the light-dependent reactions. In the light-independent reactions, carbon dioxide (CO2) from the atmosphere is converted into glucose through a series of enzymatic reactions.
The Calvin cycle, named after the scientist Melvin Calvin, is the specific pathway that carbon dioxide undergoes to be converted into glucose during the light-independent reactions. It involves a series of chemical reactions, including carbon fixation, reduction, and regeneration of the starting compound, ribulose bisphosphate (RuBP). Ultimately, glucose is synthesized from these reactions.
Therefore, the correct answer to the question is that the light-independent reactions of photosynthesis are also known as the Calvin cycle.
