We saw in Chapter 15 that a voltage gradient, also called an electric potential, exists across the plasma membrane of all cells. The potential across the plasma membrane of large cells can be measured with a microelectrode inserted inside the cell and a reference electrode placed in the extracellular fluid.
A production company is responsible for the development and filming of a specific production or media broadcast. In entertainment, the production process begins with the development of a specific project.
What does a Production Designer do? Production Designers are major heads of department on film crews, and are responsible for the entire art department.
