7352166625Emergent ProperitesProperties that a complex system has, but the individual members inside that system don't have.0
7352166626Negative feedbackA type of reaction in which a decrease in function occurs. Overall, it decreases the final product of the system and therefore stabilizing the system as a whole.1
7352166627Prokaryotic cellA cell without a nucleus, membranes, or cell organelles.2
7352166628Electron ShellThe area of the atom that surrounds the nucleus. Within each electron shell, a certain number of electrons can occupy each one.3
7352166629Valence electronAn electron that is located near the outer shell of the atom and can be lost during chemical bonding.4
7352166630Polar Covalent bondA bond between two non-metal atoms/elements. An unequal sharing of electrons is the result of this type of bonding.5
7352166631ElectronegativityThe measure of the tendency of an atom to attract electrons. On the periodic table of elements, Fluorine has the highest electronegativity.6
7352166632Hydrogen bondA bond between two polar atoms in which a hydrogen atom forms a colvalent bond with a highly electronegative atom.7
7352166633CohesionAn attractive force between similar substances.8
7352166634AdhesionAN attractive force between different substances.9
7352166635Polar moleculeA molecule that has a net dipole due to opposing charges within its makeup.10
7352166636Kinetic EnergyThe energy of an object due to motion.11
7352166637Evaporative coolingThe process in which a liquid is evaporated from a surface resulting in a decrease in temperature.12
7352166638Aqueous solutionA solution where water is the solvent.13
7352166639Hydration shellA group of water molecules surrounding an ion.14
7352166640HydrophilicThe tendency to mix with water.15
7352166641HydrophobicThe tendency to not mix with water.16
7352166642ColloidA homogeneous substance that contains particles from one substance mixed into another substance. The particles inside the substance are noncrystalline, meaning they cannot be filtered out.17
7352166643Hydronium ionH3O+ ion is formed when a hydrogen atom is added to water.18
7352166644Hydroxide ionOH- ion consists of a covalently bonded hydrogen and oxygen atom.19
7352166645Organic ChemistryThe scientific study of the structure, properties, and reactions of compounds that contain carbon.20
7352166646HydrocarbonsOrganic compounds that are only made up of hydrogen and carbon atoms.21
7352166647Structural isomersMolecules that bond in different orders, but have the same formula.22
7352166648Geometric isomersMolecular compounds that are different in respect to the arrangement of their structures. Rotation of these isomers is held to a bare minimum and two different groups must be both and the left and right side.23
7352166649EnantiomersMolecules that are identical of each other and cannot be placed right on top of each other to make the same molecule.24
7352166650Functional groupsThe portion of the molecule that is a classified group of atoms bonded together. The group is responsible for giving the molecule all the properties and characteristics it has.25
7352166651Adenosine triphosphateATP is the second most important marcomolecule behind DNA and is responsible for the primary energy currency in the cell. The molecule also creates complex molecules, contracts muscles, and generates electricity in the nerves.26
7352166652Condensation reactionTwo molecules are bonded covalently with each other and as a result, releases a small molecule into the atmosphere.27
7352166653Dehydration reactionTwo molecules are bonded covalently in which the smaller molecule that is released is water.28
7352166654EnzymesAre usually proteins that aid in chemical reactions by acting as catalysts to make the process much easier.29
7352166655MacromoleculesA large molecule formed by the combination of smaller molecules. Some examples are proteins and nucleic acids.30
7352166656MonosaccharidesThe simplest carbohydrate or a simple sugar that is all by itself and is used as a monomer for disaccharides and polysaccharides.31
7352166657DisaccharideTwo monosaccharides joined together during the process dehydration synthesis.32
7352166658Glycosidic LinkageThe formation of a covalent bond between two monosaccharides during the process of dehydration synthesis when disaccharides are formed.33
7352166659PolysaccharidesWhen three or more monosaccharides form through a dehydration reaction. They are also called polymers.34
7352166660CelluloseA polysaccharide that consists of cell walls. The make up is glucose monomers joined together by glycosidic linkages. The outer structure is very strong and is found in plants, wood, and tree bark.35
7352166661Fatty AcidIs made up of a long carbon chain and a carboxylic acid group that aids in the construction of biological structures like cell membranes.36
7352166662TriacylglycerolSynthesized when three fatty acids are joined together by a glycerol molecule. This molecule has an important function of storing energy and many plant oils are also triacylglycerols.37
7352166663Saturated Fatty AcidA type of fatty acid in which all the carbon atoms in the long chain are joint by single bonds which allows for the maximum number of hydrogen atoms to be attached. In foods this is unhealthy and not a lot of consumption is recommended.38
7352166664Unsaturated Fatty AcidA type of fatty acid in which the carbon atoms in the long chain are joint by one or more double bonds. This reduces the number of hydrogen atoms that can be attached. In foods this is seen as the healthier fatty acid to consume.39
7352166665PhospholipidThese are lipids that surround the cells and contain a hydrophilic head and a hydrophobic tail. An important class of lipids for they aid in the construction of the cell membrane. However, a phosphate group replaces the fatty acids making them not true fats.40
7352166666Amino acidThese molecules takes upon the role of being a monomer for proteins. Amino acids are compounds that hold the components of an amino group and a carboxyl group.41
7352166667Peptide bondThis bond forms particularly between two amino acids.42
7352166668SteroidsA specific type of lipid that contains four rings of carbon atoms. They play an important role in the formation and structure of different membranes. Steroids are used to treat illnesses and in other circumstances, build muscle tissue.43
7352166669PolypeptidesA chain of amino acids or a bunch of amino acids bonded together. The amino acids within polypeptides are linked covalently through peptide bonds. Proteins are made up of different polypeptides.44
7352166670Deoxyribonucleic acidDNA, is responsible for the genetic makeup of different organisms and controls replicating inherited traits. Its' structure is a twisted double helix molecule.45
7352166671Ribonucleic acidRNA, contains nucleotide monomers with a ribose sugar and the nitrogenous base. This nucleic acid functions during protein synthesis.46
7352166672PolynucleotidesA polymer in which the structure consists of many small nucleotide and a portion of it is a nucleic acid. It's a blueprint for proteins, control actions of proteins and cellular activity.47
7352166673PyrimidineCytosine, Thymine, and Uracil are the nitrogenous bases in nucleic acids called Pyrimidine.48
7352166674PurineAdenine and Guanine are the two nitrogenous bases in nucleic acids called purines.49
