Medicinal chemists that synthesize drugs to kill pathogenic protozoans aim to target a novel mechanism to promote selective toxicity. The reason there are fewer antiprotozoal drugs compared to antibacterials is that ________.
A. there are few novel molecular mechanisms in protozoa compared to human hosts since both are eukaryotes, so toxicity is an issue B. protozoans are not pathogenic compared to bacteria so developing drugs is not cost-effective C. most antiprotozoal drugs also kill bacteria so they are not given their own category D. targeting novel mechanisms in protozoans is far more costly than it is for bacterial cells

C3 plants are more susceptible to photorespiration than either C4 or CAM plants, so why do most
plants lack the C4 pathway?
a. Rubisco is more efficient in C3 plants when compared to rubisco C4 and CAM plants. b. Photorespiration is not a serious problem for most plants. c. Most plant species do not have vacuoles in their cells to store the malate generated from CO2 taken in during the night. d. There is an energetic cost to C4 and CAM pathways that only makes them advantageous in very hot and/or arid environments. e. Switching between C3, C4, and CAM photosynthesis is very difficult for most plants.
