Introduction to Neurotransmitters using AChE

Experiment #16 from Advanced Biology with Vernier

In this experiment, you will

  • Observe the reaction rate of acetylcholinesterase (AChE) found in heart tissue.
  • Compare the reaction rate of AChE from different fractions of heart tissue.
  • Observe the effect that the compound tacrine has on the reaction rate of AChE.
  • Generate a dose-response curve for the compound tacrine.
  • Estimate the effective IC50 of tacrine on heart AChE.
