Multiple choice

RuBISCO enzyme serves dual function in the chloroplast at the time of photosynthesis and forms either 3-phosphoglyceric acid or glycolic acid under various environmental conditions. Under which of the following conditions glycolic acid would be produced?

  1. In C4 plants when CO2 concentration is more than that of oxygen.

  2. In C3 plants when CO2 concentration is more than that of oxygen.

  3. In C3 plants when O2 concentration is more than that of CO2.

  4. In C4 plants when O2 concentration is more than that of CO2.

C Correct answer
Explanation

In C3 plants when O2 concentration is more than that of  CO2, glycolic acid would be produced. RuBisCO is involved in 1st major steps of carbon fixation,  in which CO2 is transformed into energy-rich molecules like glucose by plants.
