Answer:
The correct answer is active transport.
Step-by-step explanation:
Active transport is a specific type of membrane transport process that deals with the transport of solute molecules and ions against their concentration gradient which means from the region of low concentration to the high concentration region.Active transport is also known as uphill transport.
As the active transport moves solute nolecules and ions against their concentration gradient an energy source is being utilized in form of ATP molecules to carry out this uphill transport process.
