242580414Secondary structure consists of whatCoils and Folds in the polypeptide chain
242580416Tertiary Structure determined by whatInteractions among various side chains
242580421Quaternary Structure consists of whatmultiple polypeptide chains
242580424ChaperoninsProtein molecules that assist building other proteins
242580427Protein Denaturation?Protein loses its shape
242580431How do enzymes affect biochemical reactions?Catalyze
242580437What are 3 things that affect the rate at which a enzyme can work?Temperature, pH level, and Concentration of enzymes
242580441Allosteric Enzymescatalyze reactions in metabolic pathways, but also control the rates of these pathways
242580444Competitive Inhibitionthe substrate and inhibitor cannot bind to the enzyme at the same time
242580448Noncompetitive Inhibitionform of mixed inhibition where the binding of the inhibitor to the enzyme reduces its activity but does not affect the binding of substrate.
242580454Negative Feedbackoccurs when the output of a system acts to oppose changes to the input of the system,
242580460What's protein phosphorylation? How is it used in signal transduction?Adds a protein, changing its shape and cause a domino effect of reactions
242580464Signal Transduction PathwayReception, Transduction, & Response
242580469Metabolism?Sum of all chemical buildup and breakdown
242580475Carbohydrates Chemical MakeupCH20
242580480Proteins Chemical MakeupAmino Acids
242580485Nucleic Acids Chemical MakeupPhosphate Group, Nitrogen Base, Sugar
242580489ReceptionChemical message binds to protein on the cell surface
242580493TransductionBinding at the signal molecule, alters receptor protein.
242580497ResponseTransduction pathway triggers a response, Responses can vary from turning on a gene, activating an enzyme, rearranging the cytoskeleton.
242580502Symport2 species are co-transported in same direction by same transport protein
242580506Antiport2 species are co-transported in opposite directions by same transport protein
242580509ElectrogenicA net electrical imbalance, is generated across the membrane by symport or antiport of charges species
242580512ElectroneutralNo net electrical imbalance, is generated across the membrane by symport or antiport of charges species
242580515Integral ProteinsPermanently attached to the membrane ( intrinsic ) most span the phospholipid bilayer
242580518Peripheral ProteinsTemporarily attached or associated with the membrane ( extrinsic )
