What particle are nonpolar and make up the cell membrane?
Nonpolar lipids, specifically phospholipids, make up the majority of the cell membrane. These molecules consist of a hydrophilic (water-attracting) "head" and two hydrophobic (water-repelling) "tails," allowing them to form a bilayer that serves as a barrier to polar substances. This nonpolar nature is crucial for maintaining the integrity and fluidity of the membrane, enabling it to regulate the movement of substances in and out of the cell.
Where exactly in the membrane do small non polar and small polar molecules pass through?
Small nonpolar molecules pass through the lipid bilayer of the membrane, as they can easily dissolve in the hydrophobic core of the membrane. In contrast, small polar molecules can also traverse the membrane but typically do so through specific protein channels or transporters that facilitate their movement across the hydrophobic region. Overall, the lipid bilayer serves as a barrier for polar substances, while nonpolar substances can diffuse freely.
What is soluble in a nonpolar substance?
Typically nonpolar substances are soluble in other nonpolar substances. Like disolves like...
What assists the movement of polar molecules across the membrane A. Passive Transport B. Active Transport?
Polar molecules must pass through the membrane via active transport. This is because the cellular membrane is mostly nonpolar, and polar and nonpolar molecules repel each other. Only nonpolar molecule (i.e. hormones) can pass through the membrane without active transportation.
How does the structure of phospholipids linear molecules with a polar end and a nonpolar end relate to their function in the cell membrane?
The linear structure of phospholipids allows them to form a bilayer in the cell membrane due to their amphipathic nature, with the polar head facing outward towards water and the nonpolar tails facing inward. This arrangement helps create a barrier that controls the movement of substances in and out of the cell, contributing to the selective permeability of the cell membrane.

Are hydrophobic substances polar or nonpolar?
Hydrophobic substances are nonpolar.

Why iodine is more soluble in cl but less soluble in water?
Iodine is not soluble in water because iodine is nonpolar and water is polar. According to the "Like dissolve like" expression, nonpolar substances are soluble with nonpolar substances and polar substances are soluble with polar substances, but nonpolar substances are not soluble with polar substances.
How do you explain the phrase like dissolves like in terms of polar and nonpolar substances?
Polar substances dissolve other polar substances, and nonpolar substances dissolve other nonpolar substances. A polar substance cannot dissolve a polar substance and a nonpolar substance cannot dissolve a polar substance.
Do nonpolar substances get wet in water?
Nonpolar substances do not dissolve in water because water is a polar molecule. Therefore, nonpolar substances do not readily get wet in water and tend to form beads on the surface instead. This is due to the difference in polarity between water and nonpolar substances.
Can nonpolar molecules cross the cell membrane?
Yes, nonpolar molecules can cross the cell membrane through simple diffusion.
What Substances that can freely dissolve through the plasma membrane are made of?
Substances that can freely dissolve through the plasma membrane are generally small and nonpolar molecules, such as oxygen, carbon dioxide, and ethanol. These molecules are able to pass through the lipid bilayer of the plasma membrane without requiring a specific transport protein.
Is non polar soluble?
Nonpolar substances are generally soluble in other nonpolar solvents. Conversely, nonpolar substances are typically not soluble in polar solvents due to the difference in their polarity.
What does like disslove like mean?
Polar substances dissolve in polar liquids. Nonpolar substances dissovle in nonpolar liqiuds. (For more info on polar and nonpolar, refer to Chemistry)
