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.
In digital video, photography, television and film, production refers to the tasks that must be completed or executed during the filming or shooting. This includes tasks such as setting up scenes, the capture of raw footage, and usage of set designs, to name a few of the many pre-production tasks. Production is the second step in film creation. It follows the pre-production phase and evolves into the post-production. stage. See also pre-production and post production.
