Conformational changes in complex I result in the pumping of 4 protons from the matrix to the inner mitochondrial membrane. Where does the energy required to drive these conformational changes come from? a. Hydrolysis of a high energy phosphate bond in ATP b. The energy generated by the proton gradient c. The energy released as electrons are transferred from NADH to electron acceptors in the complex d. Heat energy generated by the combustion of glucose
Organic Chemistry of Metabolic Pathways
Metabolic pathways allude to the arrangement of chemical catalyzed reactions that lead to the transformation of a substance into the final product. Metabolic pathways incorporate a progression of reaction where the substrate is changed continuously and the transitional metabolites are persistently recovered.
Glucogenesis
Glucogenesis is a metabolic pathway in which glucose is produced from carbon substrates that are not carbohydrates. This process is observed in plants, animals, fungi, bacteria and other micro organisms. The general definition for glucogenesis or gluconeogenesis is as follows,
