A new microorganism is isolated from a lake and is placed into a solution of KCl. The voltage difference across its membrane is
Leona [35]

Answer: \Delta U= 1.922x10⁻²⁰ Joules

Explanation: <u>Electric</u> <u>Potential</u> <u>Energy</u> (U) is the energy a charged object has due to its location in an electric field and it will only exist with the object is charged.

<u>Voltage</u> or <u>Electric</u> <u>Potential</u> <u>Difference</u> (V) is external work done to move a charge from one point to another in a electric field.

These terms have a relationship, which is given by:

\Delta U=q\Delta V

where

q is the charge

Proton is positive and has a charge of 1.6x10⁻¹⁹C.

Unit for potential energy is Joule (J). The relation between mV and J is

1mV = 10⁻³J

Then:

V = 120x10⁻³

V = 0.12

So, for a proton to move from the negative side of a membrane to the positive:

\Delta U=q\Delta V

\Delta U=1.6.10^{-19}.0.12

\Delta U = 1.922 x 10⁻²⁰

Energy necessary to transport a proton from negative side of the membrane to the positive is 1.922 x 10⁻²⁰J.
