Under intense sunlight, ____.
A)the noncyclic pathway produces excess ATP
B)the noncyclic pathway stalls and the cyclic pathway provides extra ATP
C)excess free radicals are used to generate ATP for sugar production

E)​carbon fixation ceases and leaf cells become dormant

Quizplus · Accepted Answer

Under intense sunlight, the noncyclic pathway can become overwhelmed and stall, leading to a decrease in ATP production. In this situation, the cyclic pathway can provide extra ATP to meet the energy demands of the plant.
