Mitochondria

• Describe structural features of mitochondria.

  Inner and outer membrane, cristae, matrix
• Describe inner and outer membrane.

  Mitochondria are oval-shaped structures with an outer membrane and inner membrane. The inner membrane is highly folded, forming finger-like structures called cristae.
• Describe the cristae.

  Cristae increase the surface area available for chemical reactions to take place.
• Describe the matrix.

  The matrix is formed from the folding of the inner cell membrane.
• What does the matrix contain?

  Some of the enzymes involved in aerobic respiration and protein, lipids, ribosomes and DNA that allows mitochondria to control the production of their own protein.
• What is the function of mitochondria?

  Mitochondria are the site of aerobic respiration, which produces adenosine triphosphate (ATP).
• What is ATP essential for?

  It is a molecule that is essential for cellular activity.
• what size is the mitochondria?

  Usually 10 and 20 micro metres in diameter.
