Which process creates an important difference between \({C_3}\) and \({C_4}\) plants?
1 Respiration
2 Photorespiration
3 Photosynthesis
4 None of the above
Explanation:
Oneprocess that creates an important difference between \({C_3}\) and \({C_4}\) plants is Photorespiration. \({C_4}\) plants lack photorespiration, that is why productivity and yields are better in \({C_4}\) plants compared to \({C_3}\) plants.

What is the purpose, when the \({C_4}\) acid from the mesophyll is broken down in the bundle sheath cells?
1 In increasing the intercellular concentration of \(C{O_2}\)
2 In increasing the intracellularconcentration of \(C{O_2}\)
3 In increasing the intracellular concentration of \({O_2}\)
4 In increasing the intercellular concentration of \({O_2}\)
Explanation:
When the \({C_4}\) acid from the mesophyll is broken down in the bundle sheath cells to release \(C{O_2}\) – this results in increasing the intracellular concentration of \(C{O_2}\). In turn, this ensures that the RuBisCO functions as a carboxylase minimizing the oxygenase activity.

Assertion : Photorespiration decreases photosynthetic output Reason : In photorespiratory pathway, neither ATP nor NADPH is produced
1 Both Assertion and Reason are true and Reason is correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false.
Explanation:
Photorespiration is a wasteful pathway which also utilises the energy-assimilatory powers of light reaction.

Select the correct option regarding photorespiratory pathway.
1 Utilisation of \(C{O_2}\) synthesis of ATP, NADPH and release of \({O_2}\)
2 Utilisation of \({O_2}\), ATP, synthesis of ATP or NADPH and release of \(C{O_2}\)
3 Utilisation of \(C{O_2}\), ATP, no synthesis of ATP or NADPH and release of \({O_2}\)
4 Utilisation of \({O_2}\), ATP, no synthesis of ATP or NADPH and release of \(C{O_2}\)
Explanation:
Following the photorespiratory pathway leads to release of \(C{O_2}\), utilisation of \({O_2}\), no synthesis of sugars, ATP or NADPH.
