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?
The diagram above shows cellular activity across a cell membrane. Which two processes does this diagram most directly model?
What type of transport can use proteins but does not require energy?
