Metabolic intermediates found in living system which are essential for growth and life is called___________
Primary metabolites are the essential metabolic intermediates of the plants which help in the growth and development of the plant.
Select the odd one out from the following
Alkaloids are secondary metabolites, where as rest are primary metabolites
The most abundant component of a cell is
The Molecular Composition of Cells. Cells are composed of water, inorganic ions, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass.
Which of the following secondary metabolites is wrongly matched?
Pigments - Carotenoids,Anthocyanins
Toxins - Abrin, Ricin
Polymeric substance - Rubber, Gums
Alkaloids - Morphine, Codeine.
Which of the following are the most diverse molecules of a cell?
Four major classes of macromolecules may be identified, these are proteins, polysaccharides, lipids, and nucleic acids. Out of all macromolecules found in the cell, the proteins are most chemically and physically diverse.
Joining of repeating units to form a macromolecule is called
The naturally occurring form of amino acid in proteins
Only L-amino acids are building blocks of proteins.
The amino acids are all chiral, with the exception of glycine, whose side chain is H. As with lipids, biochemists use the L and D nomenclature. All naturally occurring proteins from all living organisms consist of L amino acids. The absolute stereochemistry is related to L-glyceraldehyde.
Which of the following biomolecules are not strictly macromolecules?
Macromolecules are giant molecules that are produced by the bonding of smaller molecules. Carbohydrates, lipids, proteins and nucleic acids are all considered to be macromolecules.
A polysaccharide is one type of macromolecule made up of monosaccharides like glucose and fructose.
Which of the following does a protein yield on hydrolysis?
Which one of the following is wrongly matched?
An enzyme is a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction. Whereas, Lipopolysaccharides (LPS), also known as lipoglycans and endotoxins, are large molecules consisting of a lipid and a polysaccharide composed of O-antigen, outer core and inner core joined by a covalent bond; they are found in the outer membrane of Gram-negative bacteria.
