Question

The sodium-glucose ______________ is a transmembrane protein and it occurs on the apical membrane epithelial cells of the small intestines. Sodium and glucose bind to this protein and are simultaneously moved into the epithelial cells using a sodium electrochemical gradient as its source of energy, and therefore this is a type of ______________ transport.

Answer 1

correct answer is symporter and active

Step-by-step explanation:

• A symporter is an integral membrane protein involved in the transport of two different molecules in the cell membrane in the same direction.
• The symporter works in the plasma membrane and the molecules are transported to the cell membrane at the same time.
• Active transport is the movement of molecules across a cell membrane from a low-concentration region to a high-concentration region against the concentration gradient.
• Active transport requires cellular energy to achieve this movement.
