Botany - Photosynthesis in Higher Plants Question with Solution | TestHub

For${\mathrm{C}}_3$plants,${\mathrm{C}\mathrm{O}}_2$fixation is carried out by enzyme RUBISCO which is highly sensitive to${\mathrm{C}\mathrm{O}}_2$concentration. Increases in${\mathrm{C}\mathrm{O}}_2$concentration increases the rate of photosynthesis and decreases in${\mathrm{C}\mathrm{O}}_2$concentration decreases the rate of photosynthesis.
