a series of enzymes and proteins in living cells through which electrons are transferred, via a series of oxidation-reduction reactions. This ultimately leads to the conversion of chemical energy into a readily usable and storable form. The most important electron transport chain is the respiratory chain, present in mitochondria and functioning in cellular respiration.
1 A well planned entity of inter- and intra-organizational care processes to solve the complexity of problems of an individual, and accompanied by systematic follow-up actions. Care chains are integrated to the extent that there are no gaps, barriers or breaks in the process leaving the older person without proper care. 2 A description of the different parts of care.... care chain / chain of care
(in biochemistry) an energy-dependent process in which certain substances (including ions, some drugs, and amino acids) are able to cross cell membranes against a concentration gradient. The process is inhibited by substances that interfere with cellular metabolism (e.g. high doses of digitalis).... active transport
n. (in psychology) a technique of *behaviour modification in which a complex skill is taught by being broken down into its separate components, which are gradually built up into the full sequence. Usually the last component in the sequence is taught first, because it is this component that is followed by *reinforcement: this is termed backwards chaining.... chaining
