What: "The fact that inhibition of an enzyme keeps the muscle contracted can be puzzling. To help them understand, the students are asked to consider analogies like a "double negative" or another from football: The neurotransmitter, acetylcholine, is like a halfback. The enzyme is the linebacker; it stops the halfback. If you block the linebacker, the halfback can keep running. Pesticides block the linebacker, allowing the signal to continue."
