10797641799CovalentA chemical bond that involves sharing a pair of electrons between atoms in a molecule0
10797641800Hydrogen bondA type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule1
10797641801PolarMolecule with partial charges2
10797641802ElectronegativeThe attraction of a given atom for the electrons of a covalent bond3
10797641803DipoleA molecule or a part of a molecule that contains both positively and negatively charged regions4
10797641804CohesionAttraction between molecules of the same substance5
10797641805Surface tensionAn inward force that tends to minimize the surface area of a liquid; it causes the surface to behave as if it were a thin skin6
10797641806AdhesionAn attraction between molecules of different substances7
10797641807Capillary ActionA process powered by adhesion that causes water molecules to move upward through a narrow tube such as the stem of a plant8
10797641808TranspirationEvaporation of water from the leaves and stem of a plant9
10797641809Specific heat capacitythe amount of heat energy required to raise the temperature of one gram of substance by one degree celcius10
10797641810Latent heat of vaporizationThe quantity of heat absorbed by a substance at the point at which it changes from a liquid to a vapor11
10797641811DenatureA change in the shape of a protein (such as an enzyme) that can be caused by changes in temperature or pH. Hydrophilic Having an affinity for water12
10797641812HydrophobicRepelled by water13
10797641813MonosaccharideA single sugar molecule such as glucose or fructose, the simplest type of sugar14
10797641814CellulosePolysaccharide found in plants that gives structure to cell walls15
10797641815GlycogenAn extensively branched glucose storage polysaccharide found in the liver and muscle of animals; the animal equivalent of starch16
10797641816CondensationType of anabolic reaction that builds polysaccharides and disaccharides from monosaccharides17
10797641817HydrolysisType of catabolic reaction that breaks down polysaccharides and disaccharides into monosaccharides18
10797641818TrigylcerideLipid molecule formed by a condensation reaction between glycerol and 3 fatty acids19
10797641819Amino acidsBuilding blocks of polypeptides20
10797641820Peptide bondBond that forms between amino acids21
10797641821enzymeA globular protein that catalyses a specific chemical reaction22
10797641822chemical reactionA process where bonds between atoms are broken and/or formed therefore modifying a substance substrate the reactant of a chemical reaction that is modified by an enzyme23
10797641823active sitethe region on the surface of an enzyme that makes contact with the substrate. The shape of the active size must exactly match the shape of the substrate24
10797641824enzyme specificityrefers to the fact that each enzyme can catalyse only one reaction25
10797641825lock and key modela model used to represent enzyme specificity. The lock represents the enzyme and the key represents the substrate. One one specific key can fit into the lock.26
10797641826activation energythe energy required for a reaction to occur (i.e. how fast the substrates are moving when they collide with each other). Enzymes lower the activation energy of reactions.27
