Document Summary

Lecture 2: all enzymes catalyze chemical reactions. How can products of chemical reactions become more energy-rich than corresponding substrate: adding work energy any type of work energy move object uphill. Make chemical reaction perform faster: decrease potential energy of substrate in its transition state. Acetyl-coa: anabolic substrate for making lipids or some hormones, energy-rich. Metabolism: conversion of chemicals within a cell. Chemical reactions in cell can only happen by active enzymes: false (not required for reaction to occur, simply a catalyst) Pgm phosphoglucomutase: mutase moves molecules around positions. Standa(cid:396)d (cid:272)onditions fo(cid:396) gi(cid:271)(cid:271)"s: 25 c, 1m or 1atm substrate and products, ph = 7, 55. 5 m h2o. Real (cid:272)onditions of gi(cid:271)(cid:271)"s has a diffe(cid:396)ent e(cid:395)uation. Change in gi(cid:271)(cid:271)"s = 0 equilibrium. Change in gi(cid:271)(cid:271)"s < 0 negative (downhill) Change in gi(cid:271)(cid:271)"s > 0 positive (uphill: almost no product. No formulas need to be memorized, all provided on test. Ion transport may be coupled to chemical reactions (ie. hydrolysis, or atp synthesis)
