- The tetanus toxin tetanospasmin blocks release of the neurotransmitter (GABA) that inhibits motor neurons and decreases muscle contraction. This causes persistence of the signal to contract and the resulting violent muscle contraction known as tetanic spasm. Compare the sustained contraction of muscle cells in rigor mortis with muscle contraction caused by the action of tetanospasmin on motor neurons. Describe experiments using marker molecules that have been done to elucidate important properties of (1) tight junctions and (2) gap junctions, and propose one additional experiment you could do with each junction to gain a greater understanding of that junction's properties.Give typing answer with explanation and conclusion Of the following molecules, which would you predict diffuses most readily across cell membranes? a. estrogen b. calcium carbonate c. potassium ions d. acetylcholine e. ligninA. Signal transduction in cells can happen in two fundamental ways once a signal arrives at the cell membrane. Using diagrams to aid your explanations, compare these two different types of signal transduction and explain why they occur differently.
