3. 1. 1 Monomers and Polymers Flashcards
What are Monomers?
Monomers are the smaller units from which larger molecules are
made.
What are Polymers?
Polymers are molecules made from a large number of monomers joined together.
Give 3 examples of Monomers.
Monosaccharides, amino acids and nucleotides are examples of monomers.
What is a condensation reaction?
A condensation reaction joins two molecules together with the formation of a chemical bond and involves the elimination of a molecule of water.
What is a hydrolysis reaction?
A hydrolysis reaction breaks a chemical bond between two molecules and involves the use of a water molecule.
What is malnutrition?
An unbalanced and inadequate diet; single biggest contributor to child mortality worldwide.
What is covalent bonding?
A covalent bond is a chemical bond that involves the
sharing of electron pairs between atoms.
What is ionic bonding?
Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions
What is hydrogen bonding?
A hydrogen bond (H-bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative atom or group.
What is a polar molecule?
A polar molecule is a chemical species in which the distribution of electrons between the covalently bonded atoms is not even.
What is metabolism?
Metabolism is the set of life-sustaining chemical reactions
in organisms.
What is anabolism?
Is the set of metabolic pathways that construct molecules
from smaller units.
What is catabolism?
The breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy.
