ssume that life on Mars requires cell potential to be 100mV, and the extracellular concentrations of the three major species are following (mmol/L): Na : 145; K : 4; Cl- : 120. Choose one species and assume that other two permeabilities are zero. Design the cell by calculating the intracellular concentration of the chosen species.

Explanation:

Given that:

The cell potential on mars E = + 100 mV

By using Goldman's equation:

Let's take a look at the impermeable cell with respect to two species;

and the two species be Na⁺ and Cl⁻

where;

z = ionic charge on the species = + 1

∴

For [Na⁺]:

For [Cl⁻]:

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
