On hot,dry days,what problem arises for C3 plants?
A) oxygen binds to rubisco's active sites preventing carbon fixation
B) with stomata open, they lose excessive water
C) too much glucose is produced
D) carbon dioxide fixes to RuBP instead of PGA
E) the electrons from water bind to ADP instead of NADPH

Question

Quizplus · Accepted Answer

On hot, dry days, C3 plants close their stomata to conserve water, leading to a decrease in CO2 levels inside the leaf. This causes oxygen to compete with CO2 for binding to rubisco, leading to photorespiration where oxygen binds to rubisco's active sites, preventing efficient carbon fixation.
