Draggable item		Corresponding Item
Transport across a membrane from low concentration to high concentration		prokaryotes
		semi-permeable

Required

1

The sodium-potassium pump is a type of active transport that uses an embedded ______________________ in the cell membrane to move ions Na+ and K+ across the cell membrane, ______________________ their concentration gradients. Because this is a form of active transport, energy is ______________________ to push the ions across the cell membrane where they are used for cellular processes. 

Some students used information they gathered from lab investigations to prepare a table. They entered the table in their lab notebooks. Which of these correctly identifies the two cells described in the table?

Cell 1 is prokaryotic, and Cell 2 is eukaryotic.
