In some conditions, they favor the microbial establishments and in some conditions, they provide some measure of general defense to the host. The vertebral host possesses some specific physical and mechanical barriers. These barriers are the first line of defense against physical, chemical, and microbial assaults. Skin, mucous membranes, epithelia of the respiratory, genitourinary, and gastrointestinal systems are examples of first-line defense barriers.

✓ 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.
