Mitochondria and Chloroplast DNA

• Mitochondria - The site of aerobic respiration within eukaryotic cells, they are just visible with a light microscope
• Mitochondria:

  • Surrounded by double-membrane with the inner membrane folded to form cristae

  
• Mitochondria:

  • The matrix formed by the cristae contains enzymes needed for aerobic respiration, producing ATP

  
• Mitochondria:

  • Small circular pieces of DNA (mitochondrial DNA) and ribosomes are also found in the matrix (needed for replication)

  
• Chloroplast:

  • Contain small circular pieces of DNA and ribosomes used to synthesise proteins needed in chloroplast replication and photosynthesis
