Question

Which of the following step/event is required to increase the intracellular concentration of $C{O}_2$ ensuring minimal oxygenase activity in dry tropical plants?

• A. Transport of fixed carbon as PGA from mesophyll cells
• B. $C_4$ acid from bundle sheath cells is broken down in the mesophyll cells to release $C{O}_2$
• C. Aspartic acid/Malic acid is translocated to bundle sheath cells through plasmodesmata
• D. ATP dependent decarboxylation of malic acid in BSCs.

Answer 1

The correct option is C

Aspartic acid/Malic acid is translocated to bundle sheath cells through plasmodesmata

Aspartic acid/Malic acid is translocated to BSC through plasmodemata, results in 3-carbon compound and $C{O}_2$
