Frogs have smooth, moist skin long, stripy legs and are likely to be found in damp habitats in the garden. and Toads have warty skin, golden eyes and prefer to crawl rather than hop.
The question is incomplete as it does not have the options which are:
Protein carrier
Lipid carrier
Porin carrier
All of the choices are correct
Answer:
Protein carrier
Explanation:
The transport of molecules through diffusion can be passive or facilitated. The facilitated diffusion in which the molecules are facilitated to cross required tow type of protein channels which are the channel proteins and the carrier proteins.
The carrier proteins are the transmembrane proteins which are specific for ions and to transport the molecules change their shape of conformation. The change in the shape is responsible for the release of ions on the other side of the membrane.
Thus, Protein carrier is correct.
