Diffusion of nonpolar molecules would not be affected by charge. Allosteric inhibition is generally a result of binding regulatory molecule at a site other than the active site.

Which of the following molecules would be blocked by a cell membrane?

Large molecules such as proteins and nucleic acids are typically blocked by the cell membrane due to their size and complexity. Small, nonpolar molecules like oxygen and carbon dioxide can easily pass through the cell membrane through simple diffusion.


Is Diffusion made of small or large molecules?

Diffusion is not a substance. It is a physical process. Diffusion is the process where there is a movement of molecules from where they are abundant to where they are scarce. A more technical definition would be: Diffusion is a process in which molecules move from a region of higher concentration to a region of lower concentration.


Why is a lipid bilayer incellmembrane considered as a barrier to the diffusion of polar molecules?

Polar molecules are hydrophilic in nature. They tend to repel from the lipid content and would easily adhere or mix with the water molecules. A lipid bi-layer consists of lipids and so it would not allow the polar molecules to pass through.


What would be least affected by defective receptor proteins on a cell membrane?

The transport of nutrients and waste across the cell membrane would be least affected by defective receptor proteins. This is because transport proteins, not receptor proteins, are primarily responsible for moving molecules across the cell membrane.


What state does diffusion eventually lead to?

Diffusion leads to the state of equilibrium, where there is an equal distribution of molecules or particles throughout a system. At equilibrium, there is no net movement of particles from one area to another because the concentration gradient has been equalized.

Would a non polar molecule dissolve in a polar molecule?

Nonpolar molecules tend to dissolve better in other nonpolar molecules due to similar intermolecular forces, while polar molecules dissolve better in other polar molecules. This is because like dissolves like - molecules with similar polarity tend to mix well together. Generally, nonpolar molecules do not dissolve easily in polar solvents.


How would you define diffusion?

Cellular diffusion is when molecules in the cell go from high concentration to low concentration to balance out the concentration. Small molecules can diffuse through the cell membrane, but larger molecules need the help of proteins. This is call facilitated diffusion.

What molecules would you expect to dissolve in water polar covalent molecules inoic molecules nonpolar convalent molecules?

ionic molecules dissolve the most. but some polar covalent molecules also do dissolve in water.


What would be the solubility of octane (C8H18) in water and why would this be?

Octane (C8H18) is nonpolar and does not have any functional groups that can interact with water, which is a polar solvent. Therefore, octane is not soluble in water. The lack of attraction between the nonpolar octane molecules and polar water molecules results in poor solubility.
