Document Summary
Biochem section 2, topic 8 notes fundamental concepts in metabolism. Differentiate b/w delta g and delta g degrees: delta g (gibbs free energy, any chemical reaction can, in principle, proceed in 1 of 2 directions, in which the. Initial concentration of 1. 0m: pressure of 1. 0 atm, temperature is 25 degrees c. Based on delta g, differentiate b/w spontaneous and non-spontaneous reactions, and reversible and irreversible reactions: spontaneous. If g of the reactants is higher than g of the products, then delta g is negative: the forward reaction is energetically favourable and the reverse reaction is energetically unfavourable. If all molecules began at equal concentration, then at equilibrium the concentration of products will be higher than that of reactants: reversible. Principle: the reaction is said to be reversible. Irreversible: for reactions far from equilibrium, delta g is a large positive or negative value, and the reaction is said to be irreversible.
