Bio molecules Quiz-19
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. How many carbon atoms generally take part in the formulation of monosaccharides?
Solution
(d) Generally, 3-7 carbon atoms take part in the formation of monosaccharides
(d) Generally, 3-7 carbon atoms take part in the formation of monosaccharides
Q2. The ‘Repeating unit’ of glycogen is
Solution
(c) Starch, glycogen, cellulose, chitin, etc. are homoglycans (glucans) containing only glucose units. Homoglycans are the polysaccharides having only one type of monosaccharide units in them.

Q3. Paraffin wax is
Solution
(a) Waxes are the esters formed between a long chain alcohol and saturated fatty acids. This material is typically pliable and soft when warm but hard and water resistant when cold, ., paraffin wax.

Q4. The following reaction is catalysed by which of the enzyme?
Solution
Cytochrome oxidases catalyses the transfer of hydrogen to oxygen, forming water in the last reaction of electron transport system

Q5. Choose the correct options
Solution
(b) Each enzyme [E] has a substrate [S] binding site in its molecule so that a highly reactive enzyme substrate complex [ES] is produced. This complex is short lived and dissociates into its product and the unchanged enzyme with an intermediate formation of the enzyme product complex [EP] The formation of the ES complex is essential for catalysis

Q7. An enzyme extract when subjected to electric field, separates into two fractions each catalyzing the same reaction. These fractions are
Solution
(b) Isoenzymes are one of the several forms of an enzyme in an individual or population that catalyse the same reaction but differ from each other in such properties as substrate affinity and maximum rates of enzyme-substrate reaction.
