  • Definition of energy coupling in Biology.

    2020-4-7 · A coupled reaction is a reaction with a common intermediate that results in energy being transferred from one side of the reaction to the other. A common example of a coupled reaction is the formation of ATP, a nucleotide that contains chemical energy that is broken down for metabolic uses. ATP stores energy in the form of phosphate bonds.

    Silane coupling agents play an important role in the preparation of composites from organic polymers and inorganic fillers such as glass, minerals, and metals. The general structure of silane coupling agents are (RO) 3-Si-R′-X, where X is an organofunctional group, R′ is a small alkylene linkage, and RO is a hydrolyzable group such as an alkoxy group (Pape, 1996).
