Question

A researcher simultaneously disrupted the activities of "Ferrochelatase" and "Chlorophyllide a oxygenase" enzymes involved in the biosynthesis of heme and chlorophyll, respectively in Arabidopsis. The researcher made the following predictions about the outcomes of the above experiments. A. The synthesis of "Chlorophyll a" from "Chlorophyllide a" will be inhibited. B. The synthesis of "Chlorophyll b" will be completely inhibited. C. The content of "Heme" molecule will be higher compared to wild-type plants. D. The metabolic flux will shift towards the biosynthesis of "Chlorophyll a". Which one of the following options represents the combination of all correct outcomes?
