Q. An agent able to produce positively charged hydrogen ions (H+). [Since the hydrogen ion is a bare proton, it usually exists in a solvated form (such as H3O+).]
Ans → acid
Explanation →
Q. The minimum energy which reacting species must possess in order to be able to form an 'activated complex', or 'transition state', before proceeding to the products.
Ans → activation energy
Explanation →
Q. Reactions in which an unsaturated system is saturated or part saturated by the addition of a molecule across the multiple bond.
Ans → addition reactions
Explanation →
Q. Organic substances occurring naturally, which are basic, forming salts with acids. The basic group is usually an amino function.
Ans → alkaloid
Explanation →
Q. The migration of a double bond in a 3-carbon system from carbon atoms one and two to carbon atoms two and three
Ans → allylic rearrangement
Explanation →
Q. The specific term used to describe carbohydrate stereoisomers differing only in configuration at the hemi-acetal carbon atom.
Ans → anomers
Explanation →
Q. An aromatic molecule or ion possesses aromaticity. Aromaticity is the special property of planar (or nearly planar) cyclic, conjugated systems having (4n+2) conjugated pi electrons.
Ans → aromatic
Explanation →
Q. A term applied to the combination of molecules of a substance with one another to form more complex systems.
Ans → association
Explanation →
Q. A term applied an object or molecule that does not possess symmetry.
Ans → asymmetry
Explanation →
Q. A a term applied to the selective synthesis of one diastereomeric form of a compound resulting from the influence of an existing chiral centre adjacent to the developing asymmetric carbon atom.
Ans → asymmetric induction
Explanation →
Q. The energy levels of electrons in an atom which may be described in terms of the four quantum numbers.
Ans → atomic orbital
Explanation →
Q. The number of particles (atoms or molecules) in one mole of any pure substance.
Ans → Avogadro's constant

Q. Initial, typically larger than the maintenance dose of a drug given to a patient at the start of pharmacotherapy.
Ans → loading dose
Explanation →
Q. The lipoproteins synthesized in the intestinal mucosal cells from the absorbed lipids are
Ans → Chylomicrons
Explanation →
Q. Destruction or removal of microorganisms in or about an object, e.g., by steam, chemical agents (alcohol, phenol, ethylene oxide gas), high-velocity electron bombardment, gamma or ultraviolet light radiation or filtration.
Ans → sterilization
Explanation →
Q. Cytokines largely produced by immune system cells that help coordinate efforts against invading pathogens
Ans → interleukins
Explanation →
Q. Transition of a suspension of solid, usually colloid, particles in a liquid (sol) to an apparent solid, jelly- like material
Ans → sol-gel transition
Explanation →
Q. The representation of a compound by two or more canonical structures in which the valence electrons are rearranged to give structures of similar probability.
Ans → resonance
Explanation →
Q. Proinflammatory molecule released by basophils and mast cells in response to stimulation by other cytokines and chemical mediators
Ans → histamine
Explanation →
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. Cytokines released by cells that have been infected with a virus; stimulate antiviral responses in nearby cells as well as the cells secreting the interferons
Ans → interferons
Explanation →
Q. Part of the orbital area in an atom where it is impossible to find an electron.
Ans → node
Explanation →
Q. When a complex molecule becomes broken apart to create two or more smaller ones.
Ans → decomposition
Explanation →
Q. The metabolic pathway concerned with the conversion of L-xylulose to D-xylulose is
Ans → Uronic acid pathway
Explanation →
Q. Plasma albumin performs the following functions
Ans → Osmotic, Transport , Nutritive
Explanation →
Q. A compound possessing hydrophobic and hydrophilic groups in its structure is known as
Ans → Ampipathic
Explanation →
Q. Method by which powder particles are compressed into a large tablet, called a slug, which is subse- quently dry-screened and compressed into a tablet.
Ans → slugging
Explanation →
Q. Process of enclosing a drug in a (micro or nano) particle (capsule, liposome, polymer).
Ans → encapsulation
Explanation →
Q. N-Acetylglutamate is required for the activation of the enzyme
Ans → Carbamoyl phosphate synthase I
Explanation →
Q. A type of inclusion containing volutin, a polymerized inorganic phosphate that appears red when stained with methylene blue
Ans → metachromatic granule

Q. Science of preparation of drugs, dosage forms, and drug delivery systems taking into account the pharmacokinetics and pharmacodynamics of the drug as well as its physical and chemical properties.
Ans → pharmaceutics
Explanation →
Q. A molecule that seeks out electrons, also known as a Lewis Acid or an electron pair acceptor.
Ans → Electrophile
Explanation →
Q. substance(s) is(are) involved in the regulation of plasma calcium level
Ans → Calcitriol , Parathyroid hormone, Calcitonin
