Bio molecules Quiz-15

Dear Readers,

NEET is the most famous and important medical entrance examination held in our country. This exam is an objective type, an offline test which includes 4 sections namely– Physics, Chemistry, Botany, and Zoology. The maximum marks that can be scored are 720 marks and have 180 questions. About half of the paper consists of questions from Biology, as the NEET exam essentially focuses on capacitating students to go for seats in medical courses. One of the most significant and crucial sections in the NEET exam is of Biology. It comprises of theories, descriptions, discoveries, diagrams, definitions, explanations of differences, and relations. The majority of the topics covered in the NEET syllabus are from the NCERT syllabus of Class 11 & 12 and other related sources become part of the rest of the syllabus. Clear Exam curates a list of articles selected by professionals who recommend the highly vital topics for NEET exams. The table below takes you directly to the respective topic where the in-depth article and the MCQs are available for an easy and productive learning experience. Prior to solving NEET question papers or practicing mock tests, you must ensure to study the basic concepts in NEET and practice a few sample questions related to this exam. Students will be covered for all their studies as the topics are available from basics to even the most advanced. .

Q1.  After grinding a living tissue in trichloroacetic acid and then straining it, you would obtain two fractions : acid soluble pool and acid insoluble fraction. Acid insoluble fraction does not contains
  •   Nucleic acids
  •   Polysaccharides
  •   Lipids
  •   Flavonoids and alkaloids
Solution
After grinding a living living tissue in trichloroacetic acid and then staining it, two fractions, acid-soluble and acid-insoluble can be found Flavonoids and alkaloids all secondary metabolites, which are not present in acid insoluble fraction

Q2. The tightly bound non-proteinaceous organic compound in enzyme, is
  •   Coenzyme
  •   Prosthetic group
  •   Cofactor
  •   Apoenzyme
Solution
Cofactors are non-proteinaceous constituents of conjugated enzyme which are associated with proteinaceous apoenzyme. These are divided into three categories. Prosthetic Groups: Organic compound tightly bound to apoenzyme. Coenzyme: Organic in nature and bound to apoenzyme at the time of course of action. Metal Ions: Inorganic in nature.

Q3.   One of the secondary structures exhibited by DNA is…..
  •   Stehenson’s model
  •   Watson-Crick model
  •   Bohr’s model
  •   Wilkenson model
Solution
Nucleic acids exhibit a wide variety of secondary structures. For example, one of the secondary structures exhibited by DNA is the famous Watson-Crick model. This model says that DNA exists as a double helix. The two strands of polynucleotides are antiparallel i.e., run in the opposite direction. The backbone is formed by the sugar-phosphate-sugar chain. The nitrogen bases are projected more or less perpendicular to this backbone but face inside

Q4.  Which of the following statements about enzymes are correct? I. Enzymes do not alter the overall change in free energy for a reaction II. Enzymes are highly specific for reactions III. The energy input needed to start a chemical reaction is called activation energy IV. Enzymes are proteins whose three dimensional shape is key to their functions
  •   I and V
  •   I, II and V
  •   II and V
  •   All of these
Solution
All the statements about enzymes are correct

Q5. Inulin is a polymer of
  •   Glucose
  •   Galactose
  •   Fructose
  •   Arabinose
Solution
  Inulin (Dahlia starch) is a polymer of fructose. It consists of 30 fructose units linked by linkage.

Q6.  The rate of physical or chemical process can be defined as
  •   The amount of reactant consumed per unit time
  •   The amount of product formed per unit time
  • The bond energy released during bond formation per unit time
  •   All of the above
Solution
Rate of a physical or chemical process refers to the amount of product formed per unit time. It can be expressed as Rate can also be called velocity if the direction is specified. Rates of physical and chemical processes are influenced by temperature among other factors. A general rule of thumb is that rate doubles or decreases by half for every 10 change in either direction. Catalysed reactions proceed at rates vastly higher than that of uncatalysed ones. When enzyme catalysed reactions are observed, the rate would be vastly higher than the same but uncatalysed reaction

Q7. Which one is not an example for hydrolases?
  •   Dehydrogenase
  •   Protease
  •   Amylase
  •   Esterase
Solution
Dehydrogenase is not an example of hydrolases. It is an example for oxidoreductases.

Q8. Enzymes catalysts differ from inorganic catalysts in which way?
  •   Enzyme catalysts are smaller in size and lesser in weight in comparision to that of inorganic catalysts
  •   Inorganic catalysts can work efficiently at temperature but enzymes catalyst cannot (except few enzymes)
  •  Inorganic catalysts can work efficiently at high pressure but enzyme catalyst cannot
  •   Both (b) and (c)
Solution
Enzyme catalysts differ from inorganic catalysts in many ways, but one major difference is that inorganic catalysts work efficiently at high temperatures and high pressures, while enzymes get damaged at high temperatures (say above ). However, enzymes isolated from organisms who normally live under extremely high temperature (., hot vents and sulphur springs), are stable and retain their catalytic power even at high temperatures (up to 80-90). Thermal stability is thus, an important quality of such enzymes isolated from thermophilic organisms

Q9. Enzymes that catalyze inter-conversion of optical, geometrical or positional isomers, are
  •   Ligases
  •   Lyases
  •   Hydrolases
  •   Isomerases
Solution
Isomerases are the enzymes which bring about rearrangement of molecular structure and catalyse the interconversion of optical, geometrical or positional isomers.

Q10.  After doing the chemical analysis of organic compounds found in living organisms, two fractions were observed namely
  •   Acid soluble pool and acid insoluble pool
  •  Carbon pool and hydrogen pool
  •   Inorganic pool and organic pool
  • Aquous pool and non-aquous pool
Solution
After doing the chemical analysis of organic compounds found in living organisms, two types of organic compounds were observed. There are filtrate (acid soluble pool) and the retentate (acid insoluble pool)
