Answer:
The correct answer is ATP/ADP transporter.
Step-by-step explanation:
Mitochondria are the cellular compositions, considered as the driving force of the cells. Each day, ATP is required by living beings to energize all of the cellular activities. Muscle contraction, nerve impulses, protein synthesis, and DNA replication are some of the important procedures, which depend upon ATP supply.
As the only small concentration of ATP is present within the body, there is a need to produce it from the expended product ADP and phosphate with the help of the complex of enzyme, known as ATP synthase situated within the mitochondria. For the ADP to reach the enzyme and for refueling of the cell by the product ATP, each molecule is required to pass through an impermeable lipid membrane, which envelopes the mitochondria. For this, the mitochondrial ATP/ADP transporter takes part to transport ATP out of the mitochondria and ADP within the mitochondria.
