Answer:
Option-C
Explanation:
The mitochondria organelle is a membrane-enclosed organelle which perform the function of producing energy in the cells.
The inner membrane layer of the mitochondria is adapted in a way that increases the surface for the enzyme which produces an energy molecule called ATP. Therefore the enzymes that synthesize the ATP molecule are known as the ATP molecule.
The ATP in the cell is produced by a complex process known as cellular respiration. The citric cycle takes place in the matrix of the mitochondria.
Thus, Option-C is the correct answer.
