How do diffusion osmosis facilitated diffusion and active transport diffusion differ?
Diffusion is the movement of molecules from an area of greater concentration to an area of lesser concentration. e.g. Exchange of gases in the lungs or body tissues. Osmosis is the diffusion of water through a semi-permeable membrane from an area of low solute to an area of high solute concentration. Faciliated diffusion is the passive transport of molecules down a concentration gradient. It is simply diffusion that involves a protein to make diffusion happen more easily across a cell membrane. Active transport is the moving of substances across the cell membrane using the cell's energy. Molecules are moved against a concentration gradient, i.e they move from an area of lesser concentration to an area of greater concentration. Tlhis is done by a carrier molecules which gets its energy from ATP.
Active transport is the process of what?
Active transport is the process of molecules being moved across a membrane using energy. Passive transport moves the molecules without using energy.
Where is laminine made in the body?
Laminin is a glycoprotein (compound where a carbohydrate is covalently linked to a protein), and like other protein molecules, it is synthesized by the DNA in the nucleus of every cell and later moved into the cytoplasm of the cell to be attached to and stored in ribosomes and the endoplasmic reticulum.

In no particular order... Dechane Cameron Woodrow Dantzler Homer Jordan Patrick Sapp (later moved to LB) Richard Moncrief (later moved to receiver) Randy Anderson Dextor McLeon (later moved to corner) Louis Solomon Vince Robinson
When As people moved west which of these became the big business on the plains?
cattle ranching
What substances is moved by diffusion?
non-polar molecules like fatty acids and retinol are transported through facilitated diffusion
What type of solute molecules may be moved by diffusion?
Many polar molecules and ions with the assistance of transport proteins.
Describe several ways molecules are moved across a plasma membrane?
Diffusion, osmosis, facilitated transport and active transport- which requires energy to work.

What is the process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins called?
The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins is called facilitated diffusion. Facilitated transport is passive and does not directly require chemical energy from ATP.
What is the process by which substances are moved through the cell membrane by a carrier molecule?
facilitated diffusion or active transport
How are glucose molecules moved into a cell and what kind of transport is this?
by diffusion and passive transportation
What substance cannot be moved into a cell by osmosis or diffusion?
Diffusion is when the particles of gas or any substance are spread out. Osmosis is two solutions are separated. Sugar molecules cannot be moved into a cell by osmosis or diffusion.
What method of transport is required when molecules must be moved against the concentration gradient?
There are multiple ways for cells to transport things across a difference in concentration. The most common process is diffusion, which is the movement from high concentration to low. Osmosis is the most popular example of this. Facilitated Diffusion is basically diffusion with the use of proteins that are specified for certain molecules. Active Transport is the method by which molecules are transported from low concentration to high concentration.
What is the a major difference between facilitated diffusion and active transport?
Simple diffusion moves molecules from an area of higher concentration to an area of lower concentration without an input of energy. Facilitated diffusion follows the same rules as regular diffusion (higher to lower concentration and no energy input), but uses protein carrier molecules to allow substances that are fat soluble to diffuse through the cell membrane.
Where can you find a diagram to show diffusion?
Diffusion is the movement of molecules across a selectively permeable layer from an area of high concentration to an area of low concentration. In cells, this can happen without the use of energy from the cell. Only molecules of certain sizes and attributes can diffuse. Others may need to be facilitated or moved via active transport (using energy). See the 'Related Links' below for diagrams and pictures.
What types of molecules are moved in osmosis?
osmosis is the diffusion of particles through a semi-permiable membrane
