Question
Chapter 11, Problem 8RQ
Summary Introduction
To determine: The term acetylcholinesterase
Introduction: Enzymes are the proteins which work as biological catalysts. These enzymes are specific for the reaction because they bind to specific substrates present in the body.
Summary Introduction
To determine: The mechanism of action of acetylcholinesterase
Introduction: Acetylcholinesterase is an important enzyme for the neurotransmission of the nerve signals. It is released at the synapses and neuromuscular junction to help transmit the nerve signals at the synapse.

- A patient has been exposed to the organophosphate pesticide malathion,which inactivates acetylcholinesterase. Which of the following symptoms would you predict: blurring of vision, excess tear formation, frequent or involuntary urination, pallor (pale skin), muscle twitching, orcramps? Would atropine be an effective drug to treat the symptoms?(See Clinical Impact 16.2 for the action of atropine.) Explain.arrow_forwardWhen the neurotransmitter acetylcholine (ACh) binds the acetylcholine receptor (a GPCR) on muscle cells, it causes them to contract. ZIGGY, a chemical analog of ACh, also binds to the same acetylcholine receptor on muscle cells, but instead causes the muscle cells to relax. For this reason, it is sometimes prescribed as a muscle relaxer. Explain in 3-4 sentences how ZIGGY could cause muscle relaxation. How can both ZIGGY and ACh bind the same GPCR? And then how can they have different effects on the cells, despite binding to the same receptor on the same cells?arrow_forwardPut the following events in chronological order. (Some of the steps may be missing.)1) Ca*+ floods into the pre-synaptic neuron.2) ch (Acetylcholine) binds to ACh receptors in the sarcolemma.3) Na+ floods into the post-synaptic muscle cell.4) The A.P arrives at the pre-synaptic terminal causing Ca+ channels to open.5) Ach from the synaptic vesicles spills into the pre-synaptic cleft.6) A post-synaptic action potential results in the muscle fiber (depolarizationarrow_forward
