The statement that is true is active transport moves against the concentration gradient.
<h3>WHAT IS ACTIVE TRANSPORT</h3>
Active transport is one of the two types of cellular transport that involves the movement of molecules against a concentration gradient. 
This moves that movement occurs from a region of lower concentration to a region of higher concentration. Since movement is against a concentration gradient, it involves input of energy (ATP). 
Therefore, the statement that is true is active transport moves against the concentration gradient.

Answer:
The two structures used in membrane transport are 1 integral membrane protein 2 peripheral membrane protein.
Explanation:
The various protein present in the plasma membrane help the later to exhibit its function to transport various solute molecules and ions across the membrane.
       Integral membrane protein such as Na+K+ATPase helps in the transport of Na+ ions inside the cell and K+ ions outside the cell against their concentration gradient.
  Peripheral membrane proteins are present in water soluble region of either extracellular region or cytoplasmic region or both.Peripheral protein also helps in the transportation of various solute molecules .
