Mitochondrion

Question 1

General function

Answer 1

1. Sites for link rn, Krebs cycle, OP

2. Generates large amt of ATP for metabolic process

Question 2

Structure of double membrane

Answer 2

Outer membrane

Inner membrane
-> highly folded to form cristae

Question 3

Describe the functions of outer membrane

Answer 3

1. Regulates the movement of biological molecules
2. Permeable to small uncharged molecules
3. Impermeable to glucose and NADH2

Question 4

Describe the function of inner membrane

Answer 4

•cristae increases SA for enzyme attachment.
-> enzyme involved in OP and e- transport

•site for attachment of stalked particle, which are components involved in OP

Question 5

Describe the function of matrix

Answer 5

Sites for Kreb’s cycle and f.a oxidation

Question 6

Contains?

Answer 6

Proteins, 70S ribosome, n.a(RNA and circular DNA)

Question 7

Describe the function of circular DNA

Answer 7

Allow mitochondrial to synthesis own proteins; multiply in no independent of cell
