Q. A bond formed from the electrostatic attraction between ions with different charges. This typically consists of a metal (cation) and a nonmetal (anion). A metal loses electrons to form a cation and some non-metal gains those electrons to form an anion.
Ans → Ionic Bond
Explanation →
Q. It occurs when a hydrogen atom has an electromagnetic attractive interaction with an electronegative atom.
Ans → Hydrogen Bonding
Explanation →
Q. An atom, or group of atoms, that is responsible for reactivity of the molecule it is a part of.
Ans → Functional Groups
Explanation →
Q. A hydrocarbon containing a carbonyl (C=O) adjacent to an ether (C-O-C) linkage.
Ans → Esters
Explanation →
Q. A molecule that seeks out electrons, also known as a Lewis Acid or an electron pair acceptor.
Ans → Electrophile
Explanation →
Q. Electronegativity is a measure of the attraction an atom has for electrons.
Ans → Electronegativity
Explanation →
Q. The process by which proteins lose their 3-D (tertiary and secondary) structure by application of an external stress, most often heat.
Ans → Denatured
Explanation →
Q. A very strong attraction between two or more atoms that are sharing their electrons.
Ans → Covalent Bond
Explanation →
Q. Isomers that differ in the order the atoms are placed. They have the same number of atoms, just in a different order.
Ans → Constitutional Isomers

Q. Name the hyperthyroidism caused by an autoimmune disease affecting thyroid function
Ans → Graves disease
Explanation →
Q. Molecules that exist only during a chemical reaction; not before or after the reaction.
Ans → intermediate
Explanation →
Q. the process of improving the octane number of straight-run gasoline by increasing the proportion of aromatic and branched chain alkanes.
Ans → catalytic reforming
Explanation →
Q. A a term applied to an atom or molecule having one or more free valencies.
Ans → radical
Explanation →
Q. The stage of replication during which various proteins bind to the origin of replication to begin the replication process
Ans → initiation of DNA replication
Explanation →
Q. A conformation in which substituents on two attached saturated carbon atoms overlap when viewed as a Newman projection.
Ans → eclipsed
Explanation →
Q. A a term applied to an atom or molecule having one or more free valencies.
Ans → radical
Explanation →
Q. A chemical reaction where water is introduced in another substance usually to separate it.
Ans → hydrolysis
Explanation →
Q. Name the type of kidney infection involving the glomeruli of the nephrons
Ans → glomerulonephritis
Explanation →
Q. Process of agglomeration that converts fine powders or granules of bulk drugs and excipients into small, free-flowing, spherical, or semi-spherical units, referred to as pellets.
Ans → pelletization
Explanation →
Q. The phospholipid that produces second messengers in hormonal action
Ans → Phosphatidylinositol

Q. The particular order in which electrons are arranged in an atom or molecule.
Ans → electronic configuration
Explanation →
Q. reactions which proceed by means of a set of repeating cyclical steps, e.g. the free radical addition of hydrogen bromide to an alkene.
Ans → chain reaction
Explanation →
Q. A bond where elections are equally shared between two atoms.
Ans → nonpolar covalent bond
Explanation →
Q. Examples of two enzymes containing zinc are
Ans → Alcohol dehydrogenase, carbonic anhydrase
Explanation →
Q. Enzymes lose the catalytic activity at temperature above 70C due to
Ans → Denaturation
Explanation →
Q. Name the class of exotoxin that targets and lyses red blood cells, as well as other cells
Ans → hemolysin
Explanation →
Q. A compound released from a natural killer cell that creates pores in the target cell through which other toxins (particularly granzymes) can gain access to the cytoplasm
Ans → perforin
Explanation →
Q. A term applied an object or molecule that does not possess symmetry.
Ans → asymmetry
Explanation →
Q. Ascorbic acid is not synthesized in man due to lack of the enzyme
