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.
In aerobic organisms, this final electron acceptor is oxygen. Molecular oxygen is a highly oxidizing agent and, therefore, is an excellent acceptor. In anaerobes, other less-oxidizing substances such as sulfate (SO 4 2â), nitrate (NO 3 â), sulphur (S), or fumarate are used.ermentation instead only uses substrate-level phosphorylation to produce ATP. The electron acceptor NAD+ is regenerated from NADH formed in oxidative steps of the fermentation pathway by the reduction of oxidized compounds.
