You discover a new cellular protein and find that there are hydrophobic amino acids scattered all along the surface of the folded protein. You know from your 181 lab that hydrophobic amino acids are generally found inside of a protein because hydrophobic amino acids cannot interact with water. Give some ideas about how/why this protein has hydrophobic amino acids on the surface.

Explanation:

Generally, hydrophobic amino acids lie in the interior of the protein to minimize the interaction with the hydrophilic (water) environment. A new cellular protein with hydrophobic amino acids on surface indicates that there is some error in the folding of the protein due to which hydrophobic amino acids come to the surface. The arrangement of amino acids determine the folding of the protein.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
