Which of the following reactions occurs during the calvin cycle?
choose all answers that apply:
a) carbon release
b) carbon fixation
c) rubp regeneration
d) carbon reduction

The correct answers are options B, C and D.

Explanation:

The Benson-Calvin cycle also known as the Calvin cycle refers to an array of chemical reactions, which occurs in chloroplasts at the time of photosynthesis. The cycle is not dependent upon light as it takes place post captivation of energy from the sunlight.  

The three prime stages of the Calvin cycle are fixation, reduction, and regeneration. The regeneration of RuBP takes place in the cycle, that is, some of the molecules of G3P further go on to produce glucose, and others recycled to reproduce the RuBP acceptor in order to continue the Calvin cycle.  

Carbon fixation also takes place, that is, carbon dioxide gets fixed and reduced to produce G3P. Thus, the reduction of carbon also taking place in the cycle.  

c.more precipitation,but only when emission levels.

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
