LIFESCI 3 Lecture Notes - Lecture 4: Oxidative Phosphorylation, Acid Dissociation Constant, Stage Name
Document Summary
Spontaneous reaction does not tell about rate of reaction (i. e. if rxn is occuring rapidly) Forward and reverse rates are equal, no change in conc of reactants and products. Steady state prevents accumulation of excess intermediates in cells. Ph where half amt molecules have donated proton and half have not low ph - don"t give up proton. Ph7 - no longer acids --> aspartate, glutamate, already gave up proton. Total energy is always the same, but energy can be converted from one form to another i. e. sunlight --> glucose. Enzymes do not change the point of equilibrium. Metabolism = sum of anabolism and catabolism activity. Glycolysis in cytoplasm --> citric acid cycle, oxidative phosphorylation in mitochondria. Acetyl coa found in many pathways (stores fat, breaks down aa), has high energy bond. When atp synthesized, you put negative groups of phosphate together (requires a lot of energy) so when you break down, a lot of energy is released.
