Mitochondria

Question 1

Mitochondria - structure

Answer 1

• has a double structure separated by a narrow inter membrane space filled with liquid.
• inner membrane folds inwards to form cristae
  - increases surface area
• includes matrix
  - has lipids and protein
• number in a cell depends on how much energy is needed.

Question 2

Mitochondria - function

Answer 2

• site of aerobic respiration in the cell
• produce ATP used for synthesis of lipids and protein
  - or exocytosis
  - or active transport
• reactions happen in the matrix and inner
  membrane
• increased surface area for attachment of
  enzymes
  - for respiration
  - increased surface area by cristae
