Question

The inner membrane of mitochondria possess finger-like projections. Give reason.

Answer 1

• Each mitochondrion is bounded by a double membrane envelope.
• The inner membrane of mitochondria contains large number of finger-like structures. These folding are known as cristae.
• Cristae increase the surface area of the inner membrane.
• Thus, more area is provided for the metabolic reactions to take place for cellular respiration.
• Thus, finger-like projections known as criste increase the surface area for maximum production of ATP.
