QuestionAnswer
What is the difference between a cofactor and a coenzyme? Cofactors are non-organic, while organic molecules are coenzymes.
Oxidoreductase Oxidation-Redox reactions
Transferase Transfer functional groups
Hydrolase Hydrolysis (addition of water)
Lyase Removal of groups of atoms without water
Isomerase Rearrangement of atoms within a molecule
Ligase Joining of two molecules
List some examples of well known coenzymes NAD+, NADP+, FMN, FAD, CoA
What are the 3 factors that influence enzymatic activity? Temperature, pH, Substrate concentration
What is denaturation of a protein, and what are some things that can cause it? Breakage of non-covalent bonds (H+ bonds)causing the protein to lose its shape and become nonfuntional. Acids, bases, heavy-metal ions, alcohol and ultraviolet radiation.

Which components of the electron transport chain pump protons? NADH dehydrogenase complex, coenzyme Q, Cytochrom oxidase complex (cyt a, cyt a3)
