Combustion of glucose (C6H₁206) is the main source of energy for animal cells: C6H₁206 (s) + 60₂(g) 6C0₂(g) + 6 H₂0 (1) One of the most important uses to which this energy is put is the assembly of proteins out of amino acid building blocks. The Gibbs free energy of formation of one peptide bond, joining one amino acid to another, is 21 kJ/mol. mol AGrxn Suppose some cells are assembling a certain protein made of 89 amino acids. (Note that the number of peptide bonds in the protein will be one less than the number of amino acids.) Calculate the maximum moles of this protein that can be assembled if 400. mg of glucose are available for combustion. Round your answer to 2 significant digits. X (37 °C) -2872. kJ ? olo Ar
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
