Assertion : Photorespiration is considered a loss to \({C_3}\) plants Reason : During this photosynthetically fixed carbon is lost.
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 process which reduces the efficiency of photosynthesis, potentially reducing photosynthetic output by \(25\% \) in \({C_3}\) plants.Photorespiration involves a complex network of enzyme reactions that exchange metabolites between chloroplast, peroxisomes and mitochondria.

Which of the following is wrong w.r.t photorespiration?
1 It releases \(C{O_2}\)
2 It uses \({O_2}\) molecule
3 It can be seen in \({C_4}\) plants
4 It can be seen in \({C_3}\) plants
Explanation:
In \({C_4}\) plants photorespiration does not occur. This is because they have a mechanism that increases the concentration of \(C{O_2}\) at the enzyme site.

During photorespiration RuBisCO uses __ as substrate.
1 \(C{O_2}\)
2 \({O_2}\)
3 \({N_2}O\)
4 \({N_2}\)
Explanation:
During photorespiraton, RuBisCO binds to \({O_2}\) by showing its oxygenase property.

Read the statements and choose the correct option. Statement A : Photorespiration decreases photosynthetic output. Statement B : In photorespiratory pathway, neither ATP nor NADPH is produced.
1 Both the Statements A and B are correct.
2 Both the Statements A and B are wrong.
3 Statement A is correct and Statement B is wrong.
4 Statement B is correct, and Statement A is wrong.
Explanation:

The process which makes major difference between \({C_3}\) and \({C_4}\) plants is
1 Glycolysis
2 Calvin cycle
3 Photorespiration
4 Respiration
Explanation:
The process of photorespiration is also called as photosynthetic carbon oxidative cycle or PCO cycle. It is a process associated with photosynthetic tissues (green plants). Photorespiration is light-dependent process which occurs in \({C_3}\) plants. In \({C_4}\) plants photorespiration does not take place.
