Question

A cell organelle with folded inner membrane is disrupted with ultrasonic breaker. Its fragments can synthesise ATP. The organelle is

• A. Ribosome
• B. Centrosome
• C. Chloroplast
• D. Mitochondrion

Answer 1

Answer: (D)

Mitochondrion

• The mitochondria is a double-membraned cell organelle, known as the powerhouse of the cell which is present in all eukaryotic cells.
• It has an outer membrane and an inner membrane.
• The inner membrane of the mitochondria is the site of the electron transport chain (aerobic respiration).
• The inner mitochondrial membrane has folds called cristae which helps in increasing the surface area.
  
• The space between the inner and outer membrane is called the inter-membrane space.
• The enzyme ATP synthase is embedded in the inner mitochondrial membrane helps in the synthesis of ATP molecule (energy currency of the cell).
• So, the correct answer is 'Mitochondria'.
