The first 3 of 30 questions. Unlock the series for the rest, each with a solution.
Q1. Lecithin, a constituent of the cell membrane, is an example of which class of lipid?
लेसिथिन, जो कोशिका झिल्ली का एक घटक है, किस वर्ग के लिपिड का उदाहरण है?
- A. Triglyceride / ट्राइग्लिसराइड
- B. Wax / मोम
- C. Steroid / स्टेरॉइड
- D. Phospholipid / फॉस्फोलिपिड
Solution
Lecithin contains phosphorus and a phosphorylated group, making it a phospholipid, the chief lipid of biological membranes.
लेसिथिन में फॉस्फोरस और एक फॉस्फोरिलित समूह होता है, जो इसे एक फॉस्फोलिपिड बनाता है, जो जैविक झिल्लियों का प्रमुख लिपिड है।
Q2. Which one of the following is an acidic amino acid?
निम्नलिखित में से कौन-सा एक अम्लीय अमीनो अम्ल है?
- A. Glutamic acid / ग्लूटामिक अम्ल
- B. Glycine / ग्लाइसीन
- C. Valine / वैलीन
- D. Lysine / लाइसीन
Solution
Glutamic acid carries an extra carboxyl group in its R-side chain, making it acidic; lysine is basic, while valine and glycine are neutral (non-polar).
ग्लूटामिक अम्ल अपनी R-पार्श्व शृंखला में एक अतिरिक्त कार्बोक्सिल समूह रखता है, जो इसे अम्लीय बनाता है; लाइसीन क्षारीय है, जबकि वैलीन और ग्लाइसीन उदासीन (अध्रुवीय) हैं।
Q3. Which one of the following is the most abundant protein in the animal world?
निम्नलिखित में से कौन जंतु जगत में सबसे प्रचुर प्रोटीन है?
- A. RuBisCO / रुबिस्को (RuBisCO)
- B. Collagen / कोलैजन
- C. Trypsin / ट्रिप्सिन
- D. Insulin / इंसुलिन
Solution
Collagen, the main structural protein of connective tissue, is the most abundant protein in the animal world. RuBisCO is the most abundant protein in the whole biosphere, while trypsin and insulin occur in comparatively small amounts.
कोलैजन, संयोजी ऊतक का मुख्य संरचनात्मक प्रोटीन, जंतु जगत में सबसे प्रचुर प्रोटीन है। रुबिस्को संपूर्ण जैवमंडल में सबसे प्रचुर प्रोटीन है, जबकि ट्रिप्सिन और इंसुलिन तुलनात्मक रूप से अल्प मात्रा में पाए जाते हैं।
