Question

Sugarcane shows high efficiency of CO2 fixation because it performs


Your Answer
A
Calvin cycle
Your Answer
B
EMP pathway
Correct Answer
C
Hatch and Slack pathway
Your Answer
D
TCA cycle

Solution

The correct option is C Hatch and Slack pathway
Sugar cane is an example for a plant that uses the C4pathway to fix CO2 in sugars and other biomolecules. The C4pathway or the Hatch and Slack pathway overcomes the tendency of the enzyme RuBisCO to wastefully fix O2 rather than CO2 during the process of photorespiration. This is achieved by ensuring that RuBisCo works in an environment where there is a lot of CO2 and very little O2.
