What are carbohydrates and lipids? - (answers)Organic compounds that are mostly composed of
three types of atom; carbon, hydrogen and oxygen
What do carbohydrates do? - (answers)provide energy, in the form of sugars like glucose and
fructose, but they also make up structures like cellulose, which form the cell wall of plant cells
What type of carbohydrate is the most important source of energy? - (answers)mono-, di- and
poly-saccharides
What are mono and disaccharides? - (answers)polar and soluble in water
What are polysaccharides? - (answers)Macromolecules resulting from polymerisation
(condensation) of sugars and are not soluble in water
Examples of monosaccharides - (answers)ribose, glucose, fructose, galactose
What forms a disaccharide? - (answers)two monosaccharides linked together by condensation
reactions with glycosidic bonds releasing one H2O molecule
Alpha glucose structure - (answers)
Beta glucose structure - (answers)
Examples of Polysaccharides - (answers)cellulose, glycogen and starch
,Monomer of Sucrose - (answers)glucose and fructose
monomer of maltose - (answers)glucose and glucose
monomer of lactose - (answers)glucose and galactose
monomer of starch - (answers)glucose
monomer of glycogen - (answers)glucose
monomer of cellulose - (answers)glucose
In animals, what carbohydrate stores energy? - (answers)glycogen
What jobs do carbohydrates have other than storing energy? - (answers)structural components
What differs the polysaccharides all made up of glucose? - (answers)they differ in the
arrangement of glucose molecules and position of the glycosidic bonds
Starch arrangement - (answers)amylopectin branched, amylose linear
What is galactose? - (answers)a sugar in milk
What is fructose? - (answers)a sugar found in fruit and honey
Main characteristic of lipids? - (answers)little to no affinity to water, mostly hydrophobic
What are the simple forms of lipids? - (answers)fat, oil and wax
,What are lipids characteristics in different solvents? - (answers)they are non-polar and insoluble
in water, but soluble in organic solvents
What are triglycerides? - (answers)the main group of lipids. They are formed by condensation
reactions between one glycerol and three fatty acids, creating ester bonds
What are the main types of triglycerides? - (answers)fats and oils. Fats are solid and oil liquid at
room temp
What are fatty acids? - (answers)carboxylic acids, possessing a -COOH functional group
What are the two basic forms of fatty acids? - (answers)saturated and unsaturated
What differs saturated from unsaturated fatty acids? - (answers)Unsaturated fatty acids have
double bonds; a monounsaturated having one, whereas a polyunsaturated having multiple
What are cis and trans isomers? - (answers)cis having the double bond elements on the same
side, trans on opposite
Benefit of lipids over carbohydrates? - (answers)Lipids have a higher energy content and can act
as thermal insulators
What is the primary protein structure? - (answers)the number and sequence of amino acids in a
polypeptide
What is the secondary protein structure? - (answers)Beta pleated sheet and alpha helix. Hydrogen
bonds between polypeptides form these structures
What is the tertiary protein structure? - (answers)three dimensional conformation. Forms when a
polypeptide folds up after translation. Stabilized by intramolecular bonds between amino acids
and polypeptides
, What is the quaternary protein structure? - (answers)linking two or more polypeptides to form a
single protein
What is the basic structure of DNA? - (answers)it is composed of three parts, a pentose sugar, a
phosphate group and a nitrogenous base
Difference in structure between DNA and RNA - (answers)RNA contains a ribose sugar instead
of deoxyribose and is also single stranded as well as having Uracil as a base instead of thymine
What are the two double helix strands held together by? - (answers)hydrogen bonds
What are hydrogen bonds? - (answers)a special type of dipole-dipole attraction between
molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a
hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and
another very electronegative atom
Why is DNA antiparallel? - (answers)so that the paired bases can face each other
what is mRNA? - (answers)Messenger RNA: Encodes amino acid sequence of a polypeptide
What is tRNA? - (answers)transfer RNA. It carries amino acids around during translation.
What is rRNA? - (answers)Ribosomal RNA. with ribosomal proteins, makes up the ribosomes,
the organelles that translate the mRNA
what is snRNA? - (answers)small nuclear RNA. with proteins, forms complexes that are used in
RNA processing in eukaryotes
What are enzymes? - (answers)biological catalysts. They are globular proteins that can speed up
a biochemical reaction. Alternative pathway
