Mitochondria

Question 1

Mitochondria - structure

Answer 1

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

Question 2

Mitochondria - function

Answer 2

• aerobic respiration in the cell
• produce ATP
  - lipid / protein synthesis
  - exocytosis / active transport
• reactions happen in matrix and inner
  membrane
• increased SA by cristae for attachment
  of enzymes and respiration
