true or false 1. Phosphoenolpyruvate carboxykinase is the enzyme involved in the carbon dioxide fixation in the mesophyll cells of C4 plants 2. The C4 pathway utilizes less ATP than C3 pathway thus enabling C4 plants to adapt to tropical temperatures. 3. Photorespiration occurs when [O2]/[CO2] is high. 4. The carboxylase activity of RuBisCO catalyzes the fixation of carbon dioxide. 5. In cyclic photophosphorylation, only ATP is produced. 6. Chlorophyll has iron as the metal center of the porphyrin ring.
