Which outcome affects plant growth rate following irreversible rubisco active site inhibition by a competitive inhibitor?

💡 Explanation

When a competitive inhibitor tightly binds to rubisco's active site, preventing CO2 substrate binding because of competitive inhibition, carbon fixation diminishes, and the plant's photosynthetic output is lessened. Therefore reduced carbon fixation impacts plant growth, as opposed to options unrelated to primary carbon assimilation pathways due to rubisco inhibition.
