Chapter 4, Problem 38CTQ
You are watching cells in a dish spontaneously contract. They are all contracting at different rates; some fast, some slow. After a while, several cells link up and they begin contracting in synchrony. Discuss what is going on and what type of cells you are looking at.

The muscle cells appear to have a greater cross- sectional area than before the training. What is the best conclusion? After 12 days of heavy strength training, muscle cells show hypertrophy. Muscle cells undergo hyperplasia after 12 days of strength training. Strength training does not cause any increase in muscle cell volume. Hyperplasia does not occur in muscle cells with heavy strength training.arrow_forwardYou wanted to prepare a fish dish for your grandfather that he loves the dried salted Codfish.

- A person ingests a fungus containing a toxin that blocks kinesin activity. How will cell transport be affected in this person?arrow_forwardSecretory vesicles fuse with the cell membrane to release their contents to the outside of the cell. In this process, the membrane of the secretory vesicle becomes part of the cell membrane. Because small pieces of membrane are continually added to the cell membrane, we would expect the cell membrane to become larger and larger as secretion continues. However, the cell membrane stays the same size. Explain how this happens.arrow_forwardWhat sort of cellular changes would you expect a sailor sick with scurvy to experience? O Their collagen (an extracellular matrix component) would be diminished, resulting in fewer binding sites for integrins. The end result would be less adherent cells. O Their collagen (a cytoskeletal fiber) would be diminished, resulting in a loss of contractile motion within the cell, affecting both cell migration and muscle function.arrow_forward
