The C₄ pathway is necessary in tropical plants because A) at high temperatures, the plants cannot maintain sufficient water levels within the cells. B) tropical plants do not have proper day/light cycles to maintain the balance of CO₂ necessary for carbohydrate storage. C) at high temperatures, the oxygenase activity of rubisco is high. D) All of the answers are correct. E) None of the answers is correct.

Question

Quizplus · Accepted Answer

At high temperatures, the oxygenase activity of rubisco increases, leading to a higher rate of photorespiration. The C4 pathway, which is what the question seems to refer to with "C₄," helps to minimize this loss by efficiently fixing CO2 even under high temperature conditions, making it particularly beneficial for tropical plants.
