Answer: The correct answer is option D
SECONDARY ACTIVE COUNTER-TRANSPORT
Explanation: Secondary active transport is a type of transport that involves molecules across the cell membrane utilizing or making use of energy in other forms than Adenosine Triphosphate (ATP).
The energy that is being made use of comes from the electrochemical gradient created by pumping ions out of the cell. This can be either via antiport or symport.
Antiport or Counter-transport means that 2 different molecules or ions are being transported at the same time but opposite directions. One of the species is allowed to flow from high concentration to a lower concentration (often Sodium) while the other species is transported simultaneously to the other side.
Example is Na+-H+ counter-transport, the example and advantage of this transporter is clearly seen in the proximal tubules of the kidneys. The mechanism for concentrating H+ is not nearly as powerful as Primary active transport, however it can transport extremely large numbers and thus making it a key in H+ homeostasis in the body.
Pernicious anemia can be defined as a medical condition in which the body of the affected individual is unable to make enough of the healthy red blood cells. The lack of the vitamin B-12 in the body of the affected person results in this condition. It is treated by giving Vitamin B-12 pills to the patient.
Hence, the answer is 'Vitamin B-12'.
