Basically Co-transport is the movement of molecules such as Glucose and Amino Acids into the epithelial cells lining the small intestine.This can be quite complicated to learn.In this case we'll look at Glucose :)
There are three different protein carriers/channelszperiodz
Firstly Sodium ions in the epithelium are taken actively out of the epithelium and into the blood by the sodium-potassium pump.This process is active transport as it uses ATP.
This in turn causes the sodium ion concentration to lower.So there is a low concentration of sodium ions in the epithelium but a high concentration in the lumen of the small intestine. Therefore the sodium ions in the lumen can now diffuse down the concentration gradient and into the epithelium, however as they do they couple with Glucose molecules in the lumen and drag them into the epithelium with them.The protein channel used is the co-transport protein.
There is now a high concentration of Glucose in the epithelium and a low concentration in the blood, therefore by Facilitated difussion the glucose molecules are taken into the blood :) Hope that helps !!
What else can I help you with?
What is cotransport and why is it an advantage to living organisms?
Cotransport is a process where two different molecules or ions are simultaneously transported across a membrane. This process is advantageous to living organisms because it allows for the coupling of the movement of molecules against their concentration gradient with the movement of molecules down their concentration gradient, resulting in the efficient transport of substances into or out of cells.
What do plants use to load sucrose?
Plants use an ekectrogenic pump, a proton pump and a con transport protein to load sucrose. The sucrose is produced by photosynthesis that turn into specialized cells in the veins of their leaves.
The movement of glucose molecules across a plasma membrane from an area of lower glucose concentration to an area of higher glucose concentration occurs due to?
active transport, specifically through a process known as secondary active transport or cotransport. This process relies on the use of energy generated by the concentration gradient of another molecule, usually sodium ions, to drive the movement of glucose against its gradient.
What three major processes of nutrient absorption must be combined with a carrier molecule for transport?
The three major processes of nutrient absorption requiring a carrier molecule for transport are facilitated diffusion, active transport, and cotransport (symport). These processes are essential for the absorption of nutrients such as glucose, amino acids, and ions in the small intestine. The carrier molecules help transport these nutrients across the cell membrane.
Different organs work together as?
When different organs work together, they work together as a system.
Is cotransport an active or passive process?
Cotransport is an active process.
What is a description of the process of cotransport?
In cotransport, a membrane protein couples the transport of two solutes.
Distinguish between the cotransport antiport and symport?
the main feature of cotransport is that neither molecule can move alone; movement of both molecules is obligatory or coupled.. When the transported molecule and cotransported ion move in the same direction, the process is said to be symport. when they move in opposite directions, the process is said antiport
What involves two active transport processes coupled together?
Cotransport
The kidney dialysis machine is an example of a mechanical?
active transport system or cotransport system.
What is cotransport and why is it an advantage to living organisms?
Cotransport is a process where two different molecules or ions are simultaneously transported across a membrane. This process is advantageous to living organisms because it allows for the coupling of the movement of molecules against their concentration gradient with the movement of molecules down their concentration gradient, resulting in the efficient transport of substances into or out of cells.
Movement of water out of the large intestine is by A osmosis B active transport C cotransport D all of the choices are correct?
B
The cotransport of protein that allows two different stances to pass through a membrane in the same direction is?
Symport is the type of cotransport that allows two different solutes to pass through a membrane in the same direction. This process involves the transport of molecules or ions in the same direction across a membrane with the help of a carrier protein. It is also referred to as coupled transport.
What do plants use to load sucrose?
Plants use an ekectrogenic pump, a proton pump and a con transport protein to load sucrose. The sucrose is produced by photosynthesis that turn into specialized cells in the veins of their leaves.
What is cotransporting?
Cotransporting, also known as secondary active transport, is a process where two different molecules or ions are transported across a cell membrane simultaneously using a single transport protein. One molecule is transported against its concentration gradient, driving the transport of the other molecule with its concentration gradient. This process typically requires the use of energy generated from the movement of ions down their concentration gradient.
How does Glucose enter the Small Intestine?
Glucose enters the small intestine through the process of digestion. When carbohydrates are broken down in the mouth and small intestine, glucose molecules are released and absorbed through the wall of the small intestine into the bloodstream.
The movement of glucose molecules across a plasma membrane from an area of lower glucose concentration to an area of higher glucose concentration occurs due to?
active transport, specifically through a process known as secondary active transport or cotransport. This process relies on the use of energy generated by the concentration gradient of another molecule, usually sodium ions, to drive the movement of glucose against its gradient.
