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 !!
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.
Cotransport is the name of a process in which two substances are simultaneously transported across a membrane by one protein, or protein complex which does not have ATPase activity. Different types of co-transport Symport When both substances are transported in the same direction the transport protein is known as a symport . Antiport When the substances are transported in opposite directions the transport protein is known as an antiport.
Oceanographers work on the ocean and some work in land and some work in laboratories.
Work is energy lost from a contained system.
No, not all oceanographers work in a lab, some may work at sea. There are various places where an oceanographer can work.
In cotransport, a membrane protein couples the transport of two solutes.
Cotransport
active transport system or cotransport system.
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

B
usually associated with a proton pump.
glucose generated by digestion of starch or lactose is absorbed in the small intestine only by cotransport with sodium, a fact that has exceptionally important implications in medicine.
d. simple diffusion
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.

transmembrane proteins like a proton pump that pumps hydrogen atoms to the extraacellular space creating a charge difference between the inside of the cell(negative charge) and the outside of the cell(positive charge) by the use of ATP. This charge difference is what allows cotransport through another transmembrane protein to occur.In a nutshell proteins with the use of ATP
