Using the video from https://www.pbs.org/video/natures-cutest-symbiosis-the-bobtail-squid-4bhtmo/
The bobtail squid and Vibrio fischeri serve as model organisms for studying cellular communication. Provideat least two examples of communication either between squid and bacteria or within bacteria from the film.
Explain a mechanism for how a nuclear-encoded protein is targeted to the inner membrane of the mitochondrion. Explain the mechanism for how a nuclear-encoded protein is targeted to the thylakoid membrane.
Describe an experiment that could be conducted to show that there is a targeting system for a nuclear encoded protein that ultimately finds its way to a specific organelle.
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.
