BIOC12H3 Lecture Notes - Lecture 2: Endergonic Reaction, Exergonic Reaction, Electronegativity
Document Summary
Lecture 2 + 3: system: collection of matter in a defined space. Ex: wearing a winter coat to keep your body warm during cold weather: endothermic: reaction absorbs heat (has + h). Increases when there is more dispersal of energy in system. Ex: degradation of large biomolecules into a large number of smaller molecules: 3rd law: system at 0k has 0 entropy. Reaction is overall favourable and spontaneous: endergonic ( g > 0): seen in reverse reactions. When all water molecule are in fixed form, the hydrogen bonding fixes their form, which causes the ice to be less dense. So, whenever possible, we should reduce the surface area. =+log: ka * kb = kw, midpoint ph = pka (also the area where graph increases the slowest, slide 38: you said all weak acids follow this patter. Many types of biochemical rxns in living organisms are maintained at a steady state that is far from eq with the environment.
