Answer #1

Answer:

3. Integral membrane proteins

Transmembrane proteins, many proteins held in the bilayer by lipid groups, and some proteins held on the membrane by unusually tight binding to other proteins cannot be released easily. These proteins are called integral membrane proteins.

Some membrane proteins do not extend into the hydrophobic interior of the lipid bilayer at all; they are instead bound to either face of the membrane by noncovalent interactions with other membrane proteins. These are called peripheral membrane proteins.

4. Diffusion.

Net movement of a substance from a region where it has a higher concentration to a region where it has a lower concentration, due to random molecular motion, is called diffusion.

5. Osmosis

6. Isosmotic

If two solutions have same osmotic pressure, they are termed isosmotic.

    Part of the vulture's protection is a stomach that is >10x more acidic than most other animals. The parietal cells of the stomach contain membrane "pumps" that transport hydrogen ions from the interior of the cell (pH=7.4) to the surrounding medium to make gastric juice (pH=0.9). The transmembrane potential between the interior of the cells and the lumen of the stomach is -75mV (inside of the cells is -75mV relative to the outside of the cells). Calculate the free energy...
