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.

What are the simple sugars made up of?
Simple sugars are made up of monosaccharide molecules, which are the most basic units of carbohydrates. Monosaccharides consist of a single sugar molecule that cannot be broken down into smaller units by hydrolysis. Examples of monosaccharides include glucose, fructose, and galactose.
What are All gas exchanges are made by?
In animals, gas exchanges are primarily made by diffusion across respiratory surfaces such as the lungs or gills. This is where oxygen enters the bloodstream and carbon dioxide exits. In plants, gas exchange primarily occurs through small openings called stomata on the leaves.
What substance has large molecules of smaller units?
Polymers are substances that have large molecules made up of repeating units called monomers. Examples include plastics, DNA, proteins, and carbohydrates.
How do ligand-gated channels facilitate the process of facilitated diffusion?
Ligand-gated channels are proteins that open in response to specific molecules, called ligands, binding to them. When these channels open, they allow certain ions or molecules to pass through the cell membrane, facilitating the process of facilitated diffusion. This means that the movement of these ions or molecules across the membrane is made easier and faster, helping maintain the balance of substances inside and outside the cell.
Why can small hydrophobic molecules cross the membrane?
Small hydrophobic molecules can cross the cell membrane easily because the membrane is made up of a lipid bilayer that repels water but allows non-polar molecules, like hydrophobic ones, to pass through.
What are large molecules made up of small molecules called?
AnswerIt can be a peptide, if it is of medium size, and the biggest is a protein molecule. A large molecule made up of amino acids may also be an enzyme.
Can small molecules that are soluble enter the blood?
yes of course your blood is partially made of small soluble molecules but im guessing that you're talking about nephrons in the kidneys and that small partially permeable membrane, in that case the answer is also "yes of course".
What are Channel and carrier proteins?
Channel proteins are on the plasma membrane, selectively transport the solutes such as ions, small and large proteins across the membrane. Carrier proteins also membrane proteins that allow diffusion of different molecules. Both proteins are chemically made up of amino acids.
What is the largest between a molecule and a atom?
Moelcules are made from atoms but a large atom is very many times the size of small molecules.
What are large molecules are made up of smaller molecules called?
Macromolecules.
What are large molecules made up of of smaller molecules called?
Macromolecules.
What are large organic molecules made from carbon?
bones
Very large molecules that are made of a chain of many smaller molecules are called?
Polymers.
A monomer is a single small molecule and a polymer is made of many small molecules How many small molecules are joined to form a dimer?
11
Giant organic molecule made of small molecules linked together?
No, it is one molecule.However some large organic molecules (i.e. polymers) are formed from small organic molecules (i.e. monomers) that bond together into long chains, forming one new large molecule. The small molecules no longer exist as individual molecules after bonding into the large molecule.
What are large molecules made of carbon hydrogen oxygen nitrogen and sometimes sulfur called?
Large molecules made of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur are called biomolecules or organic macromolecules.
How can molecules fit in ice when ice is small?
Molecules are microscopic and everything around you is made up of them...
