Organopesticides bind to acetylcholinesterase and inhibit its normal activity. What direct effect will organopesticides have on muscle tissue? Botulism food poisoning, from a toxin secreted from the bacterium Clostridium botulinum, inhibits nerve cell release of acetylcholine. What direct effect will botulism food poisoning have on skeletal muscle tissue? Curare poison binds to ACh receptors but does not activate them. What direct effect will curare have on muscle tissue? Once a muscle is excited, it will begin the process of contraction. This process is termed the excitation-contraction coupling. Explain what happens once the muscle cell is excited. As you explain, include these terms – myosin, actin, troponin, tropomyosin, SR, calcium, calcium voltage and active transport pumps, explain the steps of the contraction cycle. Explain graded potentials. How are they different from and action potential? Consider location, gates present, types of events. (2pts)A) What does IPSP mean? When will an IPSP occur?
