BIBC 102 Lecture Notes - Lecture 3: Gibbs Free Energy, Autotroph, Heterotroph
Document Summary
Bibc 102: lecture 3: a regulatory molecule that is not the enzyme"s substrate. It may be either an activator or an inhibitor of the enzyme homotropic regulation: a substrate for its target enzyme, as well as a regulatory molecule of the enzyme"s activity. G the gibbs energy change for a system under standard conditions (1 atm, 298k) the change of gibbs (free) energy for a system the difference in the energy between reactants and products. Keq: equilibrium constant (keq): a ratio that quantifies the position of a chemical equilibrium. When the equilibrium favors reactants g > 0 and keq< 1 spontaneous: a reaction is said to be spontaneous if it occurs without being driven by some outside force. Atp: adenosine triphosphate (atp) is considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need to do just about everything we do.
