8. Image source unknown. Question from the IBO .

10. e -

16. Useful light dependent reaction animations:

22. Simple Calvin Cycle animations:

24. plateau At low CO 2 concentration, rate is positively correlated with concentration CO 2 is a substrate in an enyme-catalysed light-dependent reaction.

25. At low light intensity, rate of photosynthesis is proportional to light intensity. plateau

26. Increased temp. gives increased energy and increased rate of photosynthesis Optimum temperature Above the optimum temp., enzymes are denatured and rate drops steeply. Which enzymes are used in respiration?

29. Light intensity Rate of photosynthesis What are the conditions of each of these trials?
