Document Summary

What is metabolism: the sum of biochemical processes involved in the synthesis (anabolism), breakdown (catabolism), and inter-conversion of constituents in cells and organisms. Metabolic pathways: series of enzymatic reactions leading to a products (metabolites, main metabolic pathways, carbohydrates metabolism, lipids metabolism, amino acid metabolism, nucleic acid metabolism. In order to keep our system, cell, organ, body in a steady state, we need: building blocks (nutrients, food), workers (enzymes and cofactors) and, traffic control (compartmentalization, thermodynamics and enzymatic control) Importantly, all this work is made possible by using the energy in the nutrients to transform and use it for other purposes. If the sum of the free energy change is still negative (- g(cid:524), the reactions are favourable and the exergonic reaction will force the endergonic ones. Standard free energy change (cid:523)dg "(cid:524) change (dg): standard free energy change (dgo(cid:495)(cid:524) is different from actual free energy, the standard free energy change (dgo(cid:495)(cid:524) is a constant .
