Epithelial–mesenchymal transition (EMT) is characterized by

Loss of cell–cell adhesion, is consistent with established principles of cell signaling, receptor pharmacology and cellular regulation. Experimental measurements of binding parameters, genetic loss-of-function studies and pharmacological interventions all converge on the same interpretation. Related options address neighboring concepts but do not satisfy the precise criterion stated in the question.

PSS- Sec G- Sec metabolites

Cytochrome P450 enzymes mainly function in:

Answer: B) Terpene skeleton modification. For PSS- Sec G- Sec metabolites, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) Isoprene synthesis; C) Glycoside cleavage; D) Lignin polymerization. Name the process first, then pick the option that describes it — don’t reverse cause and effect.
