Hint: In cell biology, active transport is the transfer of molecules from a region of lower concentration to a region of higher concentration through a cell membrane against the concentration gradient. Active transport is the energy-requiring method used for pumping ions and molecules through membranes against a concentration gradient.
Complete answer: Substances shift against the concentration gradient during active transport, from a region of low concentration to an area of high concentration. This process is "active" since the use of energy is needed. That is the reverse of passive transportation. In reality, cells spend most of the energy they gain in the metabolism to keep their active transport processes going. For example, most of the energy of a red blood cell is used to retain levels of internal sodium and potassium that vary from those of the surrounding environment. Active transport involves the assistance of carrier proteins that changes conformation as ATP hydrolysis occurs.
Plants take mineral ions that are transferred into root hair, where they are at a greater concentration than in the dilute solutions in the soil. Active transfer then takes place in the root in a way that the ions it requires from the soil surrounding it are taken up by the plant. Active transport of ions in a plant refers to the movement of ions against a gradient of concentration and thus requires energy supply which is derived from hydrolysis of ATP.
Therefore, the correct answer is ‘Always from hydrolysis of ATP’
So, the correct answer is “Option A”.
Note:
There are two different types of active transport: primary active transport that uses adenosine triphosphate (ATP) and secondary active transport that uses an electrochemical gradient. Sodium-potassium pump, calcium pump, mitochondrial ATP synthase are examples of primary active transport.
