Question

Which plants utilize a specialized carbon fixation enzyme and a unique cell structure to reduce the problems of photorespiration?

A. C3
B. C4
C. Desert
D. Arctic

Answer 1

C4 plants utilize a specialized carbon fixation enzyme and a unique cell structure to reduce the problems of photorespiration.

Step-by-step explanation:

C4 plants utilize a specialized carbon fixation enzyme and a unique cell structure to reduce the problems of photorespiration. These plants have a separate compartment where CO₂ combines with a 3-carbon molecule, resulting in a 4-carbon molecule. This adaptation allows for efficient use of low concentrations of carbon dioxide and helps to reduce water loss in hot climates.
