43) Which of the following is false?
A) C3, C4, and CAM plants use the light dependent reactions to harvest energy from
the sun and light independent reactions to turn that energy into sugar.
B) C3 plants use photorespiration (as opposed to the Calvin Cycle) when CO2 is low
) C4 plants utilize a specialized carbon fixation enzyme and a unique cell structure
to reduce the problems of photorespiration
D) CẢM plants perform all of the steps of photosynthesis at night to avoid e
