The initial enzyme of the Calvin cycle is

During photosynthesis,when $PGA$ is converted into phosphoglyceraldehyde,which of the following reactions occurs?

The first transitory chemical formed by the reaction between $CO_2$ and $RuBP$ is:

Regeneration of four molecules of $RuBP$ in $C_3$ cycle requires the expenditure of . . . . . . $ATP$.

State the location of the light reaction and the Calvin cycle in $C_3$ plants.

The thylakoids are removed and kept in a culture medium containing $CO_2$ and $H_2O$. If the setup is exposed to light,hexose sugars are not formed as the end product. The most appropriate reason for this is that
