The same researchers are asked to test the effects of an environmental toxin on these plant species.
They observe that when exposed to the chemical,
the rate of photosynthesis declines rapidly. Further
research shows that the thylakoid membrane was
altered, preventing H+ ions from accumulating
within the thylakoid space. How could this have a
negative influence on the rate of photosynthesis?
