1 Enzymes and Energy a product of translation 1 The wonderfully confusing antiparallel genetic code A portion of the genetic code is UUU = phenylalanine, GCC = alanine, AAA = lysine, and CCC = proline. Assume the correct code places the amino acids phenylalanine, alanine, and lysine in a protein (in that order). Which of the following TEMPLATE ( anti-sense, non-coding ) DNA sequences would substitute proline for alanine? a) 3' - AAA-CGG-TTA - 5' b) 3' - AAT-CGG-TTT - 5' c) 3' - AAA-CCG-TTT - 5' d) 3' - AAA-GGG-TTT - 5' e) 3' - AAA-CCC-TTT - 5' which reactions happen on their own? which reactions require energy input? what determines the speed of a reaction? thermodynamics kinetics energy kinetic energy potential energy mass a property of individual atoms and molecules (E = mc 2 ) first law of thermodynamics conservation of energy The total energy in the universe cannot change. E (universe) = a constant or: Δ E (universe) = 0 entropy Entropy measures the degree of disorder inherent in an ensemble of molecules. A property of an ensemble of atoms and molecules
