What is one requirement for life? correct answers The ability to efficiently an selectively catalyze chemical reactions Most biomolecules are very stable. What does this mean in terms of permitting life? correct answers Uncatalyzed transformations would be too slow to permit life What do enzymes provide a mechanism for? correct answers The regulation and coordination of these reactions What is vitalism? correct answers Belief that living things are fundamentally different from non-living things because they contain some non-physical element or are governed by different principles than inanimate objects, biochemical reactions are inseparable from living cells What experiment is one of those that indicated that the reactions of life could be separated from life? correct answers Eduard Buchner showed that dead yeast could still convert sugars into alcohol Enzymes in relation to causes of diseases correct answers The gain, loss or change of function of an enzyme can have pathological consequences. Enzymes in relation to therapeutic targets correct answers Kinase inhibitors in the treatment of cancer, Viagra, Aspirin All enzymes are proteins, with the exception of what? correct answers a small group of catalytic RNA molecules Cofactor or coenzymes tightly associated with the enzyme correct answers a prosthetic group (the difference is the degree of association) Catalysts correct answers Lower the amount of energy required for a reaction to proceed, speed up attainment of equilibrium but do not change equilibrium, are unchanged by the reaction; recycled to participate in other reactions Enzyme vs Catalyst speed correct answers Enzymes possess remarkable power, some approaching catalytic perfection Enzyme vs Catalyst conditions correct answers Many chemical catalysts that require extremes of temperature, pressure, and pH, enzymes function at physiological conditions Enzymes vs Catalysts specificity correct answers Enzymes have a higher degree of specificity, including stereospecificity, for what they act upon and produce
