Atype of transport protein found in the plasma membrane of cells lining the inside of the intestine allows sodium ions to diffuse down their concentration gradient. the ions move through the transport protein, and into the cell. these transport proteins will use the kinetic energy of the diffusing sodium ions to bring glucose into the cells as well. this transport protein would best be described as

The correct answer is "a symporter".

Explanation:

A symporter is a type of protein found within the cell's membrane that allows the transport of many different types of molecules. Symporters work in the plasma membrane allowing the entrance of large molecules to the cells (such as glucose) using the kinetic energy of diffusing ions (such as sodium). This type of transport proteins are called cotransporter, because it allows the transport of more than one molecule across the membrane.

not sure if this is what you'r looking for eubacteria and archaebacteria
