b)The structure of the mitochondrion

• - outer membrane

  - function>>>

  - compartmentalisation

  - controls entry/exit of substances into and out of the mitochondria

  - > pyruvate , oxygen, ATP move in ; ATP and carbon dioxide move out
• inner membrane

  - function>>>

  - contains ..

  - ETC

  - ATP synthase
• • inter membrane sapce

  - function>>>

  - for oxidative phosphorylation- protons are pumped into the intermembrane space and their concerntations increase
• - matrix

  - function>>>

  - contains enzymes for the link and krebs cycle

  - __contains mitochondrial DNA__
• • cristae

  - structure and function>>>

  - folding of the inner membrane

  - increases SA for oxidaitve phosphorylation and attachment of enzymes
• - ribosome

  - function→ protein synthesis
• - granules

  - what are they>>>

  - particles containing...

  - phospholipids

  - proteins

  - calcium
• DNA

  - function→codes for proteins
• • why do micrographs of mitochondria appear different to each other>>>

  - the shape of mitochondria vary depending on which plane has been cut
• ATP synthase particles - stucture and function>>>

  - embedded in the cristae

  - involved with the production of ATP
