Q.A3 (a) The biological tissues are complex, anisotropic conductors with resistive and reactive components. Fig. A3a below shows the distribution of cells in a tissue with all the relevant components shown including cell membrane (CM), extra-cellular fluid (RE) and intra-cellular fluid (R1). For such a tissues low-temperature cryopreservation employing slow-freezing and fast-thawing is considered as a viable method for the long-term preservation. However, the freezing and thawing processes themselves can induce injuries to the cells and tissue by damaging the structure and consequently functionality of the cryopreserved tissue. Bio-impedance measurements have been proposed as non-invasive method to evaluate the extent of thawing.

The equilibrium potential for a given ion (Eion) is a theoretical value. For a given concentration gradient of an ion, the equilibrium potential is the charge inside the cell required to hold an ion at that concentration. That is, it is the charge required to perfectly oppose the drive of the ion to move down its concentration gradient. So, if the concentration of Nat is higher outside the cell than inside, its equilibrium potential (ENa) must be I and if we add more sodium to the extracellular fluid, then ENa will II.
What happens across the membrane of an electricallyactive cell is a dynamic process that is hard to visualizewith static images or through text descriptions.

• Estimation of the Water Potential (Ψw) of Storage Tissue by Volume Change Method Observe these experiments in these links: https://www.youtube.com/watch?v=jTDATlaBV-o https://www.youtube.com/watch?v=k1O9jBHgsxs Estimates of water potential of various tissues have been obtained after equilibrating the tissues in solutions of different osmotic potentials. The principle depends upon finding the concentration of sucrose that would cause no change in weight of the tissue before and after an incubation period in the solution. This concentration may be assumed to have a water potential equal to that of the tissue.
One of the important uses of the Nernst equation is in describing the flow of ions across plasma membranes. Ions move under the influence of two forces: the concentration gradient (given in electrical units by the Nernst equation) and the electrical gradient (given by the membrane voltage). This is summarized by Ohms law: Ix=Gx(VmEx) which describes the movement of ion x across the membrane. I is the current in amperes (A); G is the conductance, a measure of the permeability of x, in Siemens (S), which is I/V;Vm is the membrane voltage; and Ex is the equilibrium potential of ion x. Not only does this equation tell how large the current is, but it also tells what direction the current is flowing. By convention, a negative value of the current represents either a positive ion entering the cell or a negative ion leaving the cell. The opposite is true of a positive value of the current. a.

An analog of cGMP, 8-Br-cGMP, will permeate cellular membranes, is only slowly degraded by a rod cell’s PDE activity, and is as effective as cGMP in opening the gated channel in the cell’s outer segment. If you suspended rod cells in a buffer containing a relatively high [8-Br-cGMP], then illuminatedthe cells while measuring their membrane potential, what would you observe?
