Active transport refers to the process wherein the molecules are traveling through the membrane from a lower concentration region to a high concentration region.
Further Explanation:
Membrane transport, according to cell biology, indicates the group of mechanisms that aid in regulating the movement of the molecules such as ions via the biological membrane-like lipid bilayers. The movement of the passage via the membrane is known to be due to the selective permeability of the membrane.
The transport of molecules can either be active or passive transport. Passive transport refers to the movement of the ions or other molecules across the membrane without any input of the energy.
Passive transport can be of 3 types:
• Simple diffusion
• Facilitated diffusion
• Osmosis
Active transport, on the other hand, refers to the movement of the molecules is against the concentration gradient and therefore, requires an input of energy in the type of ATP or adenosine triphosphate.
Active transport can be of 2 types:
• Primary active transport
• Secondary active transport
Primary active transport is the movement that utilizes ATP while secondary active transport utilizes an electrochemical gradient. Active transport can be observed in human physiology which is the uptake of glucose that occurs in the intestines.

active transport, membrane transport, simple diffusion, facilitated diffusion, osmosis, ATP, primary active transport, secondary active transport.
Answer:
The correct answer will be- active transport
Explanation:
The movement of molecules across the cell membrane is an important property which depends on the concentration gradient.
The natural movement of molecules usually take place from high concentration to low concentration but the movement also takes place against the concentration gradient that is from low concentration to high concentration which uses energy provided by ATP.
This movement of molecules using energy against concentration gradient is known as Active transport. This type of movement takes place in two ways: primary and secondary movement.
Thus, Active transport is the correct answer.
