Ch. 7 Pathways that harvest chemical energy 7.1 How Does Glucose Oxidation Release Chemical Energy? * In non-photosynthesizers, the most common chemical fuel -> Glucose(C 6 H 12 O 6 ) * Complex chemical transformations in the cell occur in a series of separate reactions that form a metabolic pathway. *Each reaction in a metabolic pathway is catalyzed by a specific enzyme. * Metabolic pathways are similar in all organisms, from bacteria to humans. * Many metabolic pathways are compartmentalized in eukaryotes, with certain reactions occurring inside a specific organeele. * Each metabolic pathways is regulated by key enzymes that can be inhibited or activated, thereby determining how fast the reactions will go. Cells trap free energy while metabolizing glucose - C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O + free energy - ADP + Pi + Free energy ATP - Use of ATP o Muscles or active transfortation across a membrane o Overall reaction is highly exergonic and can drive the endergonic formation of
