now known as HIF-1 alpha and ARNT. ARNT is always present in a cell, but the level of HIF-1 alpha depends on the amount of oxygen present. More oxygen means less HIF-1 alpha. That, in

How Fuel Cells Work If you want to be technical about it, a fuel cell is an electrochemical energy conversion device. Discovered in the 1800s, a fuel cell converts the chemicals hydrogen and oxygen into water, and in the process it produces electricity. The other electrochemical device that...
What is the purpose of cell transport? How can cells stop diffusion through protein channels? How do proteins that we eat move from the stomach and eventually end up in cells, and how are they used? What bulk transport process moves materials out of cells?
