◍ What are carbohydrates and lipids?.
Answer: Organic compounds that are mostly composed of three types of
atom; carbon, hydrogen and oxygen
◍ What are the 4 main elements of living organisms?.
Answer: carbon, nitrogen, oxygen, hydrogen
◍ What are atomic orbitals?.
Answer: regions where there is a high probability of finding an electron
◍ What are the first few electron configurations?.
Answer: 1s2s, 2p3s, 3p, 3d4s, 4p, 4d, 4f
◍ What do carbohydrates do?.
Answer: 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?.
Answer: mono-, di- and poly-saccharides
◍ What are primary chemical bonds?.
Answer: ionic, covalent, metallic
◍ What are mono and disaccharides?.
Answer: polar and soluble in water
◍ What are secondary chemical bonds?.
, Answer: 1. Hydrogen bonds2. Van der Waals bonds
◍ What are polysaccharides?.
Answer: Macromolecules resulting from polymerisation (condensation) of
sugars and are not soluble in water
◍ What are hydrogen bonds?.
Answer: Bonds between hydrogen atom and atoms of the most
electronegative elements (N, O, F)
◍ Examples of monosaccharides.
Answer: ribose, glucose, fructose, galactose
◍ What forms a disaccharide?.
Answer: two monosaccharides linked together by condensation reactions
with glycosidic bonds releasing one H2O molecule
◍ What are Van der Waal's bonds?.
Answer: The first type is a result of electrostatic attraction between two
permanent dipolesThe second type of Van der Waal's bond is formed due to
temporary dipoles
◍ Examples of Polysaccharides.
Answer: cellulose, glycogen and starch
◍ Monomer of Sucrose.
Answer: glucose and fructose
◍ monomer of maltose.
Answer: glucose and glucose
◍ Properties of water.
Answer: • strong hydrogen bonds• high heat capacity• solvent• needs a lot of
energy to evaporate• expands when freezes• cohesion (sticks to itself)•
adhesion (sticks to other things)
◍ monomer of lactose.
Answer: glucose and galactose
, ◍ What are the intermolecular forces in water?.
Answer: Hydrogen bonds, dipole-induced dipole forces, and London
dispersion forces
◍ monomer of starch.
Answer: glucose
◍ Ionization of water.
Answer: the transfer of a proton from one water molecule to another to
produce a hydroxide ion and a hydronium ion
◍ What are the types of concentrations?.
Answer: mass concentration, molar concentration, number concentration,
and volume concentration.
◍ What is the definition of pH?.
Answer: measure of hydrogen ion concentration of a solution to determine
acidity/basic
◍ monomer of glycogen.
Answer: glucose
◍ monomer of cellulose.
Answer: glucose
◍ In animals, what carbohydrate stores energy?.
Answer: glycogen
◍ What is the formula for pH?.
Answer: pH = -log[H+]
◍ What is chemical equilibrium?.
Answer: the rate of the forward reaction is equal to the rate of the reverse
reaction
◍ What jobs do carbohydrates have other than storing energy?.
Answer: structural components
◍ What is le chatelier's principal?.
