How do nonpolar molecules cross the cell membrane? Why can nonpolar molecules freely cross the cell membrane? Why do lipids make effective cell membranes in living cells? Why can't water go through the phospholipid bilayer? How do lipid soluble molecules cross ...
How would a protein that resides in the nonpolar interior of a membrane fold compared with the water-soluble protein? What is the difference between osmosis and diffusion? Explain briefly. Why do hydrophobic molecules interact with each other?
In the preceding figure, we can see what happens when we place carbon tetrachloride into water. Because carbon tetrachloride is a nonpolar molecule, the interactions between adjacent molecules are very weak. As a result, we might expect carbon tetrachloride to be very soluble in water. However, ...
Hsp90 is an essential molecular chaperone responsible for the folding and activation of hundreds of ‘client’ proteins, including the glucocorticoid receptor (GR). Previously, we revealed that Hsp70 and Hsp90 remodel the conformation of GR to regulate l
How are cells affected by the movement of water? Why do cells contain a small amount of ATP? How does the plasma membrane allow cell communication? Why can hydrophobic molecules cross the cell membrane? Explain how the structure and properties of phospholipids help to maintain the structure of ...

Alkanes are not soluble in water, which ishighly polar. The two substances do not meet the criterion of solubility, namely, that “like dissolves like.” Water molecules are too strongly attracted to one another by hydrogen bonds to allow nonpolar alkanes to slip between them and dissolve....
The electron cloud is largest around the hydrogen in LiH, because that hydrogen has more electrons around it than do the hydrogens in the other molecules. c. Because the hydrogen of HF is blue, we know that this compound has the most positively charged hydrogen and, therefore, it will ...
It’s known that there are two types of polymerases: distributive (they can make phosphodiesther bond between two nucleotides but can’t move along a template; many molecules of such a polymerase are needed to copy a template) and processive (they bind with a template, move on it and ...
How do vesicles transport large molecules out of a cell? Why can't small hydrophilic molecules cross the cell membrane? How do water molecules move through the cell membrane during osmosis? How are cells able to transport large molecules? How do nonpolar molecules cross the cell ...
