Barney in line at the dining commons holds out his tray as Stella heaps on more and more leftover casserole As it turns out the casserole is a little too leftover and contains bacteria that produce a toxin that acts as a calcium chelator inside Barney s skeletal muscle cells if needed look up the definition of chelator to answer this question Barney comes to you his physician for a check up You do some research about the chelator and find that it has such a high affinity for calcium that it immediately and irreversibly binds to any Ca2 ions this means the Ca ions are unavailable for any cellular functions To assess Barney you perform EMG measurements of the skeletal muscles in his arms How might Barney s EMG measurements change after ingestion of this toxin Please select all of the answers that apply to Barney s situation Please note there are multiple correct answers for this question you must select all the correct answers and no incorrect answers to earn full credit on the question Canvas auto grades this question so that you earn credit for each correct response and credit is deducted for each incorrect response O Barney s EMG will increase because the chelator does not affect the electrical events at the NMJ Calcium is involved in the EMG signal so it does affect the EMG Barney s EMG will not change because the chelator does not affect the electrical events at the NMJ O Calcium is partially involved in the EMG signal so it partially affects the EMG Barney s EMG will decrease because the chelator does not affect the electrical events at the NMJ O Calcium is not involved in the EMG signal so it does not affect the EMG
