Answer:
The correct answer will be- ATP synthase
Step-by-step explanation:
ATP is the energy-providing molecule which is utilized during the metabolic reactions of the cell so is also known as the energy currency of the cell.
The ATP is synthesized by the difference of the membrane potential generated across the membranes of the mitochondrial membrane or thylakoid membrane of the chloroplast.
The enzyme embedded in these membranes which catalyses the production of ATP molecule from ADP and Pi gaining energy by the movement of H⁺ ions (protons).
Thus, ATP synthase is the correct answer.
