Question

which of the following statements is not true about the Calvin cycle? A) the cycle is the second set of reactions in photosynthesis B) the cycle release oxygen as a byproduct. C) the cycle binds carbon atoms from carbon dioxide into organic compound.

Answer 1

A) the cycle is the second set of reactions in photosynthesis

Answer 2

Answer:

B) the cycle release oxygen as a byproduct.

Explanation:

The Calvin cycle, named after the tribute to Melvin Calvin, who discovered it, is the main route of carbon dioxide fixation. This cycle is formed by reactions that occur in the chloroplast stroma and is one of the stages of photosynthesis, as it occurs during the dark phase of photosynthesis.

This cycle does not release oxygen as a byproduct; however, the cycle binds carbon atoms of carbon dioxide to the organic compound.

The Calvin cycle, like many other metabolic cycles, regenerates its starting compound at the end of the process. This compound is 1,5-bisphosphate ribulose (RuBP), a type of sugar that is made up of five carbons and two phosphate groups.

In the Calvin cycle, we can differentiate three steps. How it takes three turns in the cycle to produce a glyceraldehyde 3-phosphate molecule.
