I think the correct graph would have light intensity on the x-axis (because light intensity is the independent variable) and a measure of photosynthetic rate (either O2 evolution or CO2 consumption) on the y-axis (because the rate of photosynthesis is the dependent variable)... hope this helps
        
                    
             
        
        
        
Catalysts lower the Activation energy for reactions. The lower the activation energy for a reaction,the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrate ms bind.
