Vedclass · Answer

(D) In $C_4$ plants,the $C_4$ cycle involves two types of cells: mesophyll cells and bundle sheath cells.$1$. In the mesophyll cells,$CO_2$ is fixed into a $4$-carbon compound (oxaloacetic acid),which is then converted into malic acid or aspartic acid.$2$. These $4$-carbon acids are transported to the bundle sheath cells,where they undergo decarboxylation to release $CO_2$ for the Calvin cycle.$3$. The remaining $3$-carbon compound,pyruvic acid,is then transported back from the bundle sheath cells to the mesophyll cells to regenerate the primary $CO_2$ acceptor,phosphoenolpyruvate $(PEP)$.

Which of the following is a $3$-carbon compound that is transported from bundle sheath cell to mesophyll cell in $C_4$ plants?
