Which of the following describes how photorespiration avoided in C-4 plants?
A)decreased concentration of phosphoglycolate
B)carbon dioxide carried toward an oxygen-rich area of the plant
C)increased concentration of ribulose-1,5-bisphosphate
D)carbon dioxide transportation from the mesophyll cells to the bundle sheath cells

Question

Quizplus · Accepted Answer

In C-4 plants, carbon dioxide is transported from the mesophyll cells to the bundle sheath cells, where it is fixed by the enzyme Rubisco. This creates a localized high concentration of carbon dioxide, which helps to avoid the oxygenation of RuBP and subsequent photorespiration.
