Question
What is the structure of mitochondria?
Solution
Mitochondria are rod-shaped cell organelle found in the cytoplasm. Each mitochondrion is a double membrane bounded structure. The outer membrane of mitochondrion is smooth. But the inner membrane of the mitochondrion is folded inwardly into the matrix of mitochondrion forming finger-like projections called Cristae. Cristae greatly increase the surface area of the inner membrane. Mitochondria also has its own DNA. It helps in the synthesis of ATP which is the energy currency of the cell.
