337371 In \({C_4}\) plants photorespiration does not occur because_

1 They have a mechanism that increases the concentration of \({O_2}\) at the enzyme site.
2 They have a mechanism that increases the concentration of \(C{O_2}\) at the enzyme site.
3 They have a mechanism that decreases the concentration of \(C{O_2}\) at the enzyme site.
4 They have a mechanism that increases the concentration of CO at the enzyme site.

337373 Read the following statements regarding photorespiration and select the total number of correct statements.
(a) In \({C_3}\) plants some \({O_2}\) does bind to RuBisCO, and hence \(C{O_2}\) fixation is increased.
(b) In the photorespiratory pathway, there is neither synthesis of sugars, nor of ATP.
(c) Photorespiration results in the release of \({O_2}\) with the utilisation of ATP.
(d) In the photorespiratory pathway there is no synthesis of ATP or NADPH.
