In class we discussed an experiment in which 2 hearts were placed in beakers of saline solution connected by a tube. The vagus nerve attached to the first heart was stimulated and contraction was monitored in both hearts. What would have happened if acetylcholinesterase was included in the saline solution in both beakers?
A) Both hearts would contract without stimulating the vagus nerve.
B) After stimulating the vagus nerve the first heart would still contract, but the second heart would not contract.
C) Neither heart would contract/contraction would be reduced after stimulating the vagus nerve.
D) Both hearts would contract more rapidly.
