The botulism toxin binds to which structure in the human body? The botulism toxin binds to the axon terminal, truly the cytoplasmic membrane of the neuron. The botulism toxin binds to the sarcoplasmic recticulum preventing the release of calcium. The botulism toxin binds to the cytoplasmic membrane of the muscle cell. The botulism toxin binds to the synaptic vessicles preventing the release of acetylcholine. Question 9 What are dental caries? MacBook Air

Briefly describe how the components of the cytoskeleton filaments get to the right location in the cell for filament formation.

Give one example of a type of protein that makes up intermediate filaments and one cell or organelle type where they might be found 8-12 nm (d) Intermediate filament © 2012 Pearson Education, Inc.

Please explain how an intermediate filament is similar and different in a normal skin cell while in a dry skin cell, dividing cell and normal skin tissue
