Which of the following conclusions can be drawn from this graph?

The optimum pH of the enzyme is 6.6.

The optimum pH of the enzyme is 5.8

The enzyme’s activity increases as pH increases 5.0 to 9.0

The enzyme’s activity is greater around pH of 8.0 .

Which of the following is the correct equation for PHOTOSYNTHESIS?

6CO₂ + 6H₂O --> 6O₂+ C₆H₁₂O₆

6CO₂+ C₆H₁₂O₆ + 6H₂O --> O₂

6O₂ + 6H₂O --> 6CO₂+ C₆H₁₂O₆

C₆H₁₂O₆ + 6O₂ ---> 6H₂O + 6CO₂
