Which structural feature allows lipids to insulate and waterproof an organism
Mice21 [21]

Answer:

Which factor best explains why lipids are important components of waterproof coatings of organisms?

Which factor best explains why lipids are important components of waterproof coatings of organisms? Lipid molecules are polar and generally soluble in water.

Is waterproof coverings a function of lipids?

Lipids can be used to store energy. Some lipids are important parts of biological membranes and waterproof coverings. Steroids synthesized by the body are lipids as well. Many steroids, such as hormones, serve as chemical messengers.

How are lipids used for insulation?

One type of lipid, the triglycerides, is sequestered as fat in adipose cells, which serve as the energy-storage depot for organisms and also provide thermal insulation

Why are lipids used for insulation?

This is because the lipid tail of molecule is hydrophobic as the water is polar. They are good insulators as they have thick fat layers that trap air inside.

How do lipids react in water?

Lipids are nonpolar molecules, which means their ends are not charged. Because they are nonpolar and water is polar, lipids are not soluble in water. That means the lipid molecules and water molecules do not bond or share electrons in any way. The lipids just float in the water without blending into it.

Thus, when this bond is broken down, ATP is converted to ADP and Pi ( inorganic phosphate) and  releases large amount of energy.
