Answer:
The CO2 acceptor concentration would increase when the CO2 is cut off, but decrease when the light is cut off.
Explanation:
Calvin's light-independent reactions cycle breaks down on three basic stages: fixation, reduction, and regeneration.
All organisms need energy to perform life functions, and energy that is released is reused in other ways. Some plants have evolved mechanisms to increase the CO2 concentration in their leaves under hot and dry conditions.
