Answer:
Bongkrekic acid is produced by pseudomonas cocovenenans in fermented coconut. It is a respiratory toxin i.e. it interferes with the normal respiration mechanism of body. It inhibits ADP/ATP translocase whose primary function is to transport ATP produced in mitochondria to cytoplasm so that rest of the cell can be supplied with energy. When inhibited, the cells become devoid of energy and all major biochemical pathways begin to shut down.
Since respiration is important for every part of the body bongkrekic acid poisoning does a systemic damage to the body. Liver and kidney failure can occur because they are not able to perform their functions. This results in gastrointestinal symptoms like vomiting, nausea, diarrhea etc. Severe edema can also be observed and ultimately multiple organ failure can occur which is fatal.
