Useful light dependent reaction animations:
Simple Calvin Cycle animations:
plateau
CO2 is a substrate in an
enyme-catalysed lightdependent reaction.
At low CO2 concentration, rate is
positively correlated with concentration
plateau
At low light intensity, rate of photosynthesis is
proportional to light intensity.
Optimum
temperature
Increased temp.
gives increased
energy and
increased rate of
photosynthesis
Above the
optimum temp.,
enzymes are
denatured and
rate drops steeply.
Which enzymes are
used in respiration?
Rate of photosynthesis
What are the conditions of each of these trials?
Light intensity
