You are studying a bacterial strain that is an obligate aerobe. The bacteria can do some fermentation and produce lactic acid as an end product, but normally only when starved for oxygen and can’t survive on fermentation alone. Your rival dumps a chemical into your prize culture. This chemical binds to the first protein in the electron transport chain, locking it into a fully reduced and inhibited state permanently. Describe the predicted consequences of this poison on the function of...
