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.
Why is a lipid bilayer incellmembrane considered as a barrier to the diffusion of polar molecules?
The lipid bilayer is made up of nonpolar hydrophobic tails that repel polar molecules, making it difficult for them to pass through. Polar molecules are also unable to dissolve in the hydrophobic environment of the lipid bilayer, further hindering their diffusion across the membrane. This selective barrier allows the cell to control the movement of polar molecules in and out of the cell.
What to many monomers make up when they are linked together?
When many monomers are linked together, they form a polymer. Polymers are large molecules made up of repeating units called monomers, which are attached together through chemical bonds. This process is known as polymerization.
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, small molecules that are soluble can enter the blood through passive diffusion, facilitated diffusion, or active transport across cell membranes. Once in the blood, these molecules can be circulated throughout the body to reach target tissues or be metabolized and eliminated by the body's excretory systems.
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 made up of of smaller molecules called?
Macromolecules.
What are large molecules are made up 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.
What are molecules on the cell membrane responsible for?
Letting different molecules in and out of a cell. Chemicals including steroid hormones, reactants and products of respiration...ect. the chemicals have to pass through the phospholipid bilayer (which is made from phosphates and fatty acid chains) molecules pass through the bilayer through passive diffusion, facilitated diffusion and active transport.
