Metabolism

________ provides a mechanism for the production of energy.

deoxyribose

The sugar found in polynucleotides is either ribose (a monosaccharide pentose) or 2 ________.

polysaccharide

In a(n) ________, the individual monosaccharides are linked by a glycosidic bond.

distinct components

A nucleotide has three chemically ________.

Oils

________ have a lower melting point (e.g., gingelly ________) and hence remain as ________ in winter.

protein thread

A(n) ________ does not exist throughout as an extended rigid rod.

fatty acid

A(n) ________ has a carboxyl group attached to an R group.

homopolymer

A(n) ________ has only one type of monomer repeating ‘ n a number of times.

Plant cell walls

________ are made of cellulose.

threads

They are ________ (literally cotton ________) containing different monosaccharides as building blocks.

acid insoluble fraction

The ________ has only four types of organic compounds i.e., proteins, nucleic acids, polysaccharides, and lipids.

steady state

The ________ is a non- equilibrium state.

long chains of sugars

Polysaccharides are ________.

peptide bond
