Electron Transport Chain or ETC is a series of compounds which transfer electrons to electron transfer from electron donors thru a redox reaction which in turn, couples this electron transfer with the proton transfer (H+ ions) through the membrane.
<span>The negatively charge particles that chlorophyll loses to the transport chain or ETC are replinished by the molecules of water. Water is divided and electrons from it are used to replace the electron found in the chrlorophyll pigment.</span>
The velocity of a stream usually increases downstream. The gradient (slope) of the stream typically decreases but gravity, elimination of bed roughness and an increase in the amount of water from the entry of tributaries tends to increase the velocity.
It doesn't stay up there for long and there are several different ways that it can get up there. hope this helps:)
Complementary mRNA strand would be the following:
AUCAUCAUC.
3 Repeating codons of AUC, on the mRNA strand.
