Document Summary
Energy production: catabolic pathways, anabolic pathways. Stock market analogy: when stocks are good and increasing the company benefits, when stocks are poor and decreasing, the company does not do as well. Think of this in terms of catabolic pathways and metabolism. When your body"s energy metabolism is low, the fuel catabolism is low and not very effective and vise versa when it is high/working effectively. Energy metabolism in cells: oxygen & carbon-based fuels catabolism & atp synthesis atp - . Cellular energy metabolism based around atp" molecule (adenosine triphosphate). Hydrolysis of single phosphate bond in atp molecule, produces adp: this releases a packet of energy, used to drive all kinds of important processes. Muscle contraction, to ion pumping, synthesis of macromolecules (protein, dna, rna) As atp is hydrolyzed to adp, it has to be re-synthesized. This is done through many catabolic reactions (occur in cytosol and mitochondria)
