the solubility of benzophenone in solvents is still a matter of interest, especially, why is benzophenone insoluble in water. In contrast to the widespread ability of water to dissolve many substances, benzophenone is a counterexample due to the special relationship between ...
The plasma membrane is a lipid bilayer that consists of phospholipids and a number of proteins that are embedded in the membrane. The plasma membrane only allows certain molecules to pass through.Answer and Explanation: Become a member and unlock all Study Answers Start today. T...
Hydrophobic substances repel the polar ions in water and resist wetting. The low surface energy of the coatings means that the cohesive forces in the water are strong enough to make the water bead up and not spread across the surface of the coating. Oleophobic means oil molecules are “repel...
A membrane which allows certain substances to pass through it, but not others is called a selectively permeable membrane. View Solution Study the set-up given in the diagram and answer the following questions: Why is the membrane called semipermeable membrane? View Solution The plasma membrane ...
(a) Why are membranes impermeable to most substances? (b) How do proteins function to make membranes selectively permeable? Why can't certain molecules diffuse across the membrane? How do organisms alter the fluidity of the lipid bilayer? How do the lipids of the...
Step-by-Step Solution1. Definition of Plasma Membrane: The plasma membrane, also known as the cell membrane, is a biological membrane that separates and protects the interior of the cell from the external envir

Which interactions are involved in establishing and holding the three-dimensional structure of a protein? a. salt bridge and disulfide bonds b. hydrogen bonds c. hydrophobic effects d. all of these choicesWhat is the anti-hemophilic factor in the ...
Detergents are chemicals that have the ability to disperse solids in a liquid. Said solids are generally impurities and dirt that adhere to the object and which are cleaned by detergents. Detergents generally have wetting capacity and can keep such solid residues ...
How do hydrophobic vs. hydrophilic substances generally (and differently) cross the plasma membrane? Which proteins are involved in facilitated diffusion? Specify whether each of the items listed is hydrophilic or hydrophobic by grouping them into the appropriate box. Triglyce...
