what is the name of the cycle represented by a circle in the diagram

The name of the cycle is kelvin cycle or C3 cycle

Explanation:

Kelvin cycle represent the dark reaction of photosynthesis that occurs in the stroma of chlorplast.

        During C3 cycle carbon dioxide is fixed into glucose molecules by the help of several enzyme catalyzed sequential reactions.The ATP and NADPH formed during light reaction is utilized to carry out C3 cycle.

     ATP helps in the phosphorylation of phosphoglyceric acid to diphosphoglyceric acid by the catalytic activity of phosphoglycerate kinase.

  NADPH act as reducing agent which reduces phosphoglyceric acid to phosphoglyceraldehyde(PGALD).

         PGALD then undergoes further enzymatic reactions to generate glucose (C6H12O6).
