Which process limits overall glucose production in C3 photosynthetic pathways under high heat combined with water stress?

💡 Explanation

When high heat and water stress occur, photorespiration increases in C3 plants because RuBisCO binds more readily to O2 than CO2 reducing carbon fixation efficiency. Therefore, increased photorespiration limits glucose production results, rather than other listed options, which trigger under different constraints.
