How does atrazine disrupt photosynthesis
WebPhotorespiration is avoided in C4 plants because. a. these plants separate the formation of a four-carbon molecule from the rest of the Calvin cycle in different cells. b. these plants carry out only anaerobic respiration. c, the enzyme PEP functions to maintain high CO2 concentrations in the bundle-sheath cells. WebWhat type of organism is most affected by atrazine? Plants - it is a phytotoxin Inhibits photosynthesis by competing with plastoquinone II at its binding site in the preocess of electron transport in photosystem II. What is plastoquinone?
