Question

Describe the structure of cell organelle known as 'Power house of cell'?

Answer 1

Mitochondria are called the "powerhouse of cell" as they are involved in the formation of ATP during the aerobic cellular respiration.

Their structure shows the following details:

1. They are surrounded by double membranes, as an outer membrane and an inner membrane.
2. The space between the two membranes is called peri-mitochondrial space.
3. The inner membrane shows the infoldings called cristae that bear the ATP synthases complex. It has enzymes for the electron transport chain.
4. Interior to the inner membrane, the matrix is present that contains the ribosomes, DNA and enzymes.
5. The ribosomes are of 70S types and DNA is circular
