Question

Identify the molecules (a) and (b) shown below and select the right option giving their source and use.

• A. (b) Molecule - Herion; Source - Cannabis sativa; Use -Depressant and slows down body functions
• B. (b) Molecule - Dopamine; Source - Altropa belladona; Use - Produces hallucinations
• C. (a) Molecule - Morphine; Source - Papaver somniderum; Use - Sedative and pain killer
• D. (a) Molecule - Cocaine; Source - Erythroxylum coca; Use - Accelerates the transport of dopamine

Answer 1

Answer: (D)

(a) Molecule - Cocaine; Source - Erythroxylum coca; Use - Accelerates the transport of dopamine

• The molecule ''a'' is the chemical structure of cocaine, an opioid that is obtained from the seeds of the poppy plant (Papaver somniferum).
• Coca alkaloid or cocaine is a cannabinoid that is obtained from the coca plant Erythroxylum coca, native to South America.
• It interferes with the transport of the neurotransmitter dopamine i.e, accelerates the transport of dopamine. It has a potent stimulating action on the central nervous system, producing a sense of euphoria and increased energy.
• The excessive dosage of cocaine causes hallucinations. Whereas, the molecule ''b'' is the chemical structure of a cannabinoid molecule. These are the chemicals that interact with cannabinoid receptors present in the brain.
• 
  
• So, the correct answer is option D.
