Diffusion
Water soluble molecules often enter or exit a cell through a process called facilitated diffusion. This process involves the movement of molecules across the cell membrane with the help of specific protein channels or carriers.
Phospholipids are the organic molecules in cell membranes that permit the diffusion of lipid-soluble materials. They have a hydrophobic tail that repels water and a hydrophilic head that interacts with water, creating a bilayer structure that allows for the passage of lipid-soluble molecules.
When two materials are infinitely soluble in each other, it means that they can mix together in any proportion without forming separate phases. This indicates a complete miscibility between the two materials, allowing them to form a homogeneous solution at any concentration.
No, the rates of absorption and diffusion are not constant for all molecules. They depend on factors like molecular size, charge, solubility, and membrane permeability. Larger molecules, charged molecules, and less lipid-soluble molecules typically have slower rates of absorption and diffusion compared to smaller, uncharged, and lipid-soluble molecules.
Water-soluble molecules are absorbed through passive diffusion or facilitated transport in the intestines, while fat-soluble molecules are absorbed with the help of bile salts and form micelles for absorption through simple diffusion in the small intestine. No specific transporters are needed for fat-soluble molecules due to their ability to pass through the cell membrane easily, unlike water-soluble molecules which require specific transporters for absorption.
Substances of a higher concentration (or with higher level of water molecules) are more soluble than lower concentration liquids.
Water-soluble molecules diffuse through the cell membrane by passing through protein channels or transporters that are embedded in the membrane. These channels and transporters allow the molecules to move across the membrane, from an area of high concentration to an area of low concentration, without requiring energy.

All small and polar molecules and all ionic compounds are soluble in water.
The process in which food containing large, insoluble molecules is broken down in to small, water soluble molecules (which can be absorbed by the body) is called digestion.
In diffusion, molecules move from an area of high concentration to an area of low concentration. This movement is driven by random kinetic energy and does not require a membrane or cellular energy. Small, nonpolar molecules such as oxygen, carbon dioxide, and lipid-soluble compounds diffuse easily across cell membranes.
Yes, lipid soluble molecules diffuse into a cell more rapidly than water soluble molecules. This is because the cell membrane is primarily made up of lipids, so lipid soluble molecules can easily pass through the lipid bilayer, while water soluble molecules need specific channels or transporters to facilitate their entry into the cell.

no some materials are soluble but not gels. Like salt which is soluble
