Please help, and in a hurry! Moore et al. state that CAM plants do
not exhibit photorespiration. I don't buy it. If carbon dioxide
is secondarily fixed in the mesophyll chloroplasts by rubisco during
the day, and these are normal chloroplasts containing thylakoids,
there should be plenty of oxygen ergo photorespiration. I am at a
loss to explain the statement in Moore et al. to my class of budding
college botanists. Please respond to the bio.net so that my students
can read the responses, too. Thanks.
