electron transport

electron transport

n.
The movement of electrons from one electron carrier to another in a series of oxidation-reduction reactions. Electron transport is used in the light reactions of photosynthesis and in the final stage of cellular respiration to produce ATP from ADP, phosphate, and the energy that is released as an electron is moved from one carrier to another with a lower level of energy.

PSII reaction centers (Fryer et al., 1995), energy trapping and transfer in PSII (Levasseur et al., 1990; Jiang et al., 2006) and electron transport (Van Heerden et al., 2004, 2007; Strauss et al., 2006) have been demonstrated to be target sites with low temperature injury.
