Vedclass · Answer

(B) The correct answer is $B$. Both statements $A$ and $B$ are correct.Photorespiration is a wasteful process in $C_3$ plants.In $C_3$ plants,some $O_2$ binds to $RuBisCO$ instead of $CO_2$,which decreases the efficiency of $CO_2$ fixation.In this pathway,$RuBP$ binds with $O_2$ to form one molecule of phosphoglycerate $(3C)$ and one molecule of phosphoglycolate $(2C)$.During the photorespiratory pathway,there is no synthesis of sugars,$ATP$,or $NADPH$. Instead,it leads to the release of $CO_2$ and the consumption of $ATP$.

Statement $A$: Photorespiration decreases photosynthetic output.
Statement $B$: In photorespiratory pathway,neither $ATP$ nor $NADPH$ is produced.
