Effective pumping of $CO_2$ into bundle sheath cells

Vedclass · Answer

(C) ${C_4}$ plants are more efficient at photosynthesis under low $CO_2$ concentrations because they possess a specialized mechanism called the $C_4$ cycle or Hatch-Slack pathway.In this pathway,$CO_2$ is initially fixed in mesophyll cells by the enzyme $PEP$ carboxylase to form a $4$-carbon compound (oxaloacetate).This $4$-carbon compound is then transported to the bundle sheath cells,where it is decarboxylated to release a high concentration of $CO_2$ around the enzyme $Rubisco$.This effective pumping mechanism ensures that $Rubisco$ is saturated with $CO_2$,thereby minimizing photorespiration and allowing photosynthesis to continue even when atmospheric $CO_2$ levels are low.

Photosynthesis in ${C_4}$ plants is relatively less limited by atmospheric $CO_2$ levels because
