The Molecular Toxicology claim to fame segment is keen on the molecular mechanisms whereby chemicals cause harmfulness. There are a few explanations behind this intrigue. Right off the bat, mechanisms of toxicity can reveal central parts of science. Hence, poisons, for example, cyanide and rotenone were utilized to reveal the presence of the Krebs cycle, a focal segment of cellular energy metabolism. Programs in the field of molecular toxicology study the effects of chemicals on living microscopic organisms.
