The Mechanisms in Semipermeable Membranes  and Neurons

Abstract

A membrane can be permeable to a particular molecule if the pores on  the membrane are sufficiently larger than the molecule in the  corresponding dimension. It also depends on the electromagnetic polarity of the molecule  as well as the membrane. For example an ion or a polarized molecule may  not pass through a polarized membrane due to long range  electromagnetic interactions. Some large molecules collected at a membrane can act  as secondary membranes inhibiting some other molecule from passing to  the membrane in some cases it is also possible that the secondary membranes   increase the permeability by neutralising the polarity of the primary  membrane. A similar situation is possible in neurons also. An example application  of these mechanisms can be found in diabetes which can occur due to the  damage of a membrane. Consequently the sugar molecules, probably acting  as secondary membrane, can lose their action and pass through the  primary membrane and can further damage other parts. A possible remedy for  this can be the repair of the damaged membrane. An evidence for this is that 90-95% of Diabetes cases are not Insulin dependent [1].
