Cell Structure: Mitochondria

Question 1

What sort of membrane does the mitochondria have?

Answer 1

= double membrane
= outer mitochondrial membrane
= inner mitochondrial membrane
= between the membranes intermembrane space

Question 2

What is the fluid of the mitochondria called?

Answer 2

Matrix.
= enzymes involved in respiration are found
= semi-rigid material containing protiens, lipids and traces of DNA- allows mitochondrian to control protien production.

Question 3

What are the folds in the inner mitochondrial membrane called?

Answer 3

= cristae
= increases surface area for attachment of enzymes involved in respiration.

Question 4

What can also be found in the mitochondria?

Answer 4

= loop of mitochondrial dna- genes for enzymes involved in aerobic respiration
= contaisn mitochondrial ribosomes- synthesise protiens encoded by the mitochondrial dna
