Chapter 12, Problem 22RQ

Summary Introduction

To review:

The damage to the peripheral nerve fibers is reversible as compared to the damage of the CNS (central nervous system) fibers.

Introduction:

The injuries cause damage to the cells or tissues in the affected region and it may be reversible or may regenerate in some parts of the body while in others the damaged cells are not regenerated. The peripheral nervous system includes the nerves that are arising from the brain known as cranial nerves and the ones originate from the spinal cord are called spinal nerves. The central nervous system includes the brain and the spinal cord.

Biology Question

✓ Details Draw a protein that is embedded in a membrane (a transmembrane protein), label the lipid bilayer and the protein. Identify the areas of the lipid bilayer that are hydrophobic and hydrophilic. Draw a membrane with two transporters: a proton pump transporter that uses ATP to generate a proton gradient, and a second transporter that moves glucose by secondary active transport (cartoon-like is ok). It will be important to show protons moving in the correct direction, and that the transporter that is powered by secondary active transport is logically related to the proton pump.
