Free Sneak Peek

Here is a sneak peek of the questions included in this test set. Test your preparation by viewing the answer and detailed explanation before starting the timed exam.

When a living tissue is ground with Trichloroacetic Acid (Cl_3CCOOH) and filtered, what represents the Acid-Soluble Pool vs Acid-Insoluble Fraction?

जब एक जीवित ऊतक को ट्राइक्लोरोएसेटिक एसिड (Cl_3CCOOH) के साथ पीसकर फ़िल्टर किया जाता है, तो एसिड-घुलनशील पूल बनाम एसिड-अघुलनशील अंश क्या दर्शाता है?

Acid-Soluble: Proteins and DNA; Acid-Insoluble: Simple sugarsएसिड-घुलनशील: प्रोटीन और डीएनए; अम्ल-अघुलनशील: सरल शर्करा

Acid-Soluble Pool (Filtrate): Biomicromolecules (MW 18 to 800 Da: amino acids, monosaccharides, nucleotides); Acid-Insoluble Fraction (Retentate): Biomacromolecules (MW > 10,000 Da: proteins, nucleic acids, polysaccharides, and lipids)एसिड-घुलनशील पूल (फ़िल्टर): बायोमाइक्रोमोलेक्युलस (MW 18 से 800 Da: अमीनो एसिड, मोनोसैकराइड, न्यूक्लियोटाइड); एसिड-अघुलनशील अंश (रेटेंटेट): बायोमैक्रोमोलेक्युलस (मेगावाट> 10,000 दा: प्रोटीन, न्यूक्लिक एसिड, पॉलीसेकेराइड और लिपिड)

Acid-Soluble: Inorganic salts only; Acid-Insoluble: Water onlyएसिड-घुलनशील: केवल अकार्बनिक लवण; अम्ल-अघुलनशील: केवल पानी

Both fractions contain identical moleculesदोनों अंशों में समान अणु होते हैं

Correct Answer: Option B

Explanation:

Grinding with trichloroacetic acid yields: 1. Acid-soluble pool (micromolecules < 800 Da), 2. Acid-insoluble retentate (macromolecules > 10,000 Da: proteins, nucleic acids, polysaccharides, and membrane lipid vesicles).

ट्राइक्लोरोएसिटिक एसिड के साथ पीसने से उपज मिलती है: 1. एसिड-घुलनशील पूल (माइक्रोमोलेक्युलस 10,000 Da: प्रोटीन, न्यूक्लिक एसिड, पॉलीसेकेराइड, और झिल्ली लिपिड वेसिकल्स)।

Why are 'Lipids' found in the Acid-Insoluble Macromolecular Fraction despite having molecular weights not exceeding 800 Da?

आणविक भार 800 Da से अधिक न होने के बावजूद एसिड-अघुलनशील मैक्रोमोलेक्यूलर फ्रैक्शन में 'लिपिड' क्यों पाए जाते हैं?

Lipids are giant polymers of amino acidsलिपिड अमीनो एसिड के विशाल पॉलिमर हैं

Lipids have molecular weights over 100,000 Daलिपिड का आणविक भार 100,000 Da

Lipids precipitate as inorganic calcium saltsसे अधिक होता है लिपिड अकार्बनिक कैल्शियम लवण के रूप में अवक्षेपित होते हैं

Lipids are membrane components that fragment during grinding into water-insoluble vesicular aggregates that are retained on the filter clothलिपिड झिल्ली घटक होते हैं जो पीसने के दौरान पानी में अघुलनशील वेसिकुलर समुच्चय में टुकड़े हो जाते हैं जो फिल्टर कपड़े पर बने रहते हैं

Correct Answer: Option D

Explanation:

Lipids are small molecules (MW < 800 Da), but their hydrophobic nature causes cell membranes to form insoluble vesicles during homogenization, retaining them in the retentate.

लिपिड छोटे अणु होते हैं (मेगावाट

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Focused chapter-wise CBT practice builds the speed, mental stamina, and analytical discipline required to ace CUET, JEE Main, NEET UG, NDA, CA Foundation, and College Entrance Exams.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन

Traditional paper tests take weeks to grade, by which time the student has forgotten their thought process. TargetExams provides instant scorecards and step-by-step solutions while the conceptual puzzle is still fresh.
