Which molecule is regenerated in the regeneration phase of the calvin cycle? without regeneration of this molecule

Ribulose bisphosphate (RuBP)

Explanation:

Hello,

Calvin cycle is a biochemical process that accounts for the carbohydrate production done by the plants. It is divided in three stages fixation (enzyme RuBisCO incorporates carbon dioxide into an organic molecule), reduction, and regeneration in which Ribulose bisphosphate (RuBP), the molecule that starts the cycle, is regenerated so that the cycle can continue.

Best regards.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
