Ans-B.
Explanation: Alkaloids are a diverse group of naturally occurring organic compounds that contain basic nitrogen atoms. They are found in various plant species as well as some animals and fungi. Alkaloids often have pharmacological effects on humans and other organisms, which can range from medicinal to toxic.
| Alkaloid | Function(s) |
|---|---|
| Nicotine | 1. Stimulant: Nicotine acts as a central nervous system stimulant, leading to increased alertness and arousal. It is the primary psychoactive component in tobacco products. |
| 2. Addiction: Nicotine is highly addictive, leading to dependence in individuals who use tobacco products. | |
| 3. Neurotransmitter modulation: Nicotine interacts with nicotinic acetylcholine receptors in the brain, influencing neurotransmitter release and synaptic transmission. | |
| Morphin | 1. Analgesic: Morphine is a potent pain reliever used for moderate to severe pain management. It acts on opioid receptors in the central nervous system to reduce pain perception. |
| 2. Sedation: Morphine can induce sedation and a sense of euphoria, making it valuable for managing pain and distress in medical settings. | |
| 3. Respiratory depression: Morphine can depress respiratory function, especially at higher doses, which requires careful monitoring in clinical use. | |
| Nimbidin | 1. Anti-inflammatory: Nimbidin, derived from neem (Azadirachta indica), exhibits anti-inflammatory properties, making it useful in traditional medicine for treating inflammatory conditions. |
| 2. Antimicrobial: Nimbidin has antimicrobial activity against various pathogens, including bacteria, fungi, and viruses, contributing to its use in herbal remedies for infections. | |
| 3. Antioxidant: Nimbidin acts as an antioxidant, protecting cells from oxidative stress and potential damage caused by free radicals. |
