Question

Write the odd one out of the following and give a reason for your choice : Sugars,PGA,RUDP,light reaction.

Answer 1

Dear student,

Light reaction does not belong to the group because rest all i.e, sugar, PGA and RuDP , belongs to Dark reaction.
Here in the formation of hexose sugar in dark reaction, three molecules of CO₂ combines with three molecules of RuDP (Ribulose diphosphate) to form six molecules of PGA (phosphoglyceric acid).

Regards.
