10. At low light intensity, rate of photosynthesis is proportional to light intensity. plateau
11. plateau At low CO 2 concentration, rate is positively correlated with concentration CO 2 is a substrate in an enyme-catalysed light-dependent reaction.
12. 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?

Photosynthesis title, definition and equation.
Photoactivation of chlorophyll – electrons are excited and return to their original state, releasing oxygen.
Light intensity affects rate of photosynthesis.
CO2 affects rate of photosynthesis. CO2 is the substrate in carbon fixation (Calvin cycle) – rubisco is the enzyme.
Temperature affects the rate of photosynthesis. Remember enzyme theory. Enzymes used in respiration: rubisco is the main one. ATP synthase can also be denatured.
