1 Anemometer: A tool used by meteorologists to measure wind speeds. 2  Speed: How fast or slowly something is moving.  Revolutions per minute (rpm): How many times something goes around in a complete circle, or rotates, in one minute. The anemometer you will make in this exercise measures the wind speed in rpm.
Electron acceptors participate in electron-transfer reactions. In this context, the oxidizing agent is called an electron acceptor and the reducing agent is called an electron donor. A classic oxidizing agent is the ferrocenium ion Fe(C. 5H.
1 Carbon dioxide or acetic acid are the most commonly used electron acceptor in methanogenesis.  Microbes capable of producing methane are called methanogens. They have been identified only from the domain Archaea - a group that is phylogenetically distinct from eukaryotes and bacteria.
