12. (a) Using Eq. AQ=CAV and the data in the Table, calculate the number of ions entering the axon during
the action potential, per meter of nonmyelinated axon length. (The charge on the ion is 1.6 x 10-19 coulomb.)
(b) During the resting state of the axon, typical concentrations of sodium and potassium ions inside the axon
are 15 and 150 millimole/liter, respectively. From the data in the Table, calculate the number of ions per
meter length of the axon.

- Helicobacter pylori (H. pylori) is a helically-shaped bacterium that is usually found in the stomach. It burrows through the gastric mucous lining to establish an infection in the stomach's epithelial cells (see photo). Approximately 90% of the people infected with H. pylori will never experience symptoms. Others may develop peptic ulcers and show symptoms of chronic gastritis. The method of motility of H. pylori is a prokaryotic flagellum attached to the back of the bacterium that rigidly rotates like a propeller on a ship. The flagellum is composed of proteins and is approximately 40.0 nm in diameter and can reach rotation speeds as high as 1.50 × 103 rpm. If the speed of the bacterium is 10.0 um/s, how far has it moved in the time it takes the flagellum to rotate through an angular displacement of 5.00 × 107 rad?arrow_forwardHelicobacter pylori (H. pylori) is a helically-shaped bacterium that is usually found in the stomach.
