A classical example of active transport is the transport of sodium ions in frog skin from the epithelium to the corium, i.e. into the body. The principal ionic component in the organism of a frog, sodium ions, is not washed out of its body during its life in water. That this phenomenon is a result of the active transport of sodium ions is demonstrated by an experiment in which the skin of the common green frog is fixed as a...

Antimicrobial peptides (ranatuerin-lC, -2Ca and -2Cb, ranalexin-lCa and -ICb, 20 to 30 amino acid residue peptides) and five related temporin 13-amino-acid residue peptides were isolated from green frog and partially purified on a Cig column k = 214 nm) using a 100/0 -> 79/21 (at 10 min) -> 37/63 (at 60 min) water (0.1% TFA)/acetonitrile gradient [1292]. Fractions collected were further purified on a C4 column using 40-min gradients from 70/30 -> 45/55 water (0.1% TFA)/ acetonitrile. A table of amino acid sequences and molecular weights is presented. 

Orientation via chemical cues may be more important in some species than in others. For example, Oldham (1966, 1967) studied homing and orientation in American toads Bufo americanus) and green frogs Rana clamitans). Oldham (1966) partially destroyed the olfactory tracts of 99 American toads and used 99 intact toads treated as operational controls. An additional 112 toads were left untreated. The toads were then transported to a point of land between two pools. About the same frequencies of returns occurred to the pools. Oldham concluded that olfaction was not necessary for orientation and homing in American toads. However, since only a portion of the olfactory system was destroyed, it is possible that olfaction was still involved in homing and orientation.
