|
Carbon reduction
|
Explanation:
Detailed explanation-1: -The Calvin cycle reactions can be divided into three main stages: carbon fixation, reduction, and regeneration of the starting molecule.
Detailed explanation-2: -Oxygen acts as a byproduct of the light reaction of photosynthesis. Thus, oxygen is released in a light reaction, not in the Calvin cycle.
Detailed explanation-3: -27.1. 1.1 Calvin cycle enzymes. Calvin cycle is operated by 11 different enzymes that catalyze 13 reactions. The “key” regulatory enzymes are RuBisCO, FBPase, SBPase, and PRK.
Detailed explanation-4: -Explanation: The conversion of carbon dioxide into glucose takes place through a light-dependent reaction, also called the Calvin cycle. It is performed in the stroma of the chloroplast.
