Read the following statements and choose the following option: 1. Photorespiration does not synthesize sugars 2. In photorespiration occuring in C3 plants RuBP is converted to C3 plants 3. There is a parabolic relationship between incident light and CO2 fixation rates at low light intensities. 4. The light saturation occurs at 10 per cent of the full sunlight.

Options

  1. AOnly 1 is correct
  2. BBoth 1 and 2 is correct
  3. COnly 3 is correct
  4. DBoth 3 and 4 is incorrect

Correct answer

A. Only 1 is correct

Step-by-step solution

In the photorespiratory pathway, there is neither synthesis of sugars, nor of ATP. Rather it results in the release of CO2 with the utilisation of ATP.
