Lecture 8

Question 1

Mitochondria structure

Answer 1

Double membrane and in the cytosol of most eukaryotic cells.

2) their number can increase by fission and decrease by fusion
3) 1-10 um
4) tubular organelles
5) outer membrane, inner membrane, intermenbrane soace. With Cristae.
6) 5-10 circular DNA and prokaryote like ribosomes.

Question 2

Localisation of mitochondria

Answer 2

Can move inside cytoplasm.

Entrocytes

Secretary cells

Muscle fibres

Question 3

Structure of outer membrane of mitochondria

Answer 3

1) contains integral membrane proteins in which channels through which molecules and ions can move out

Question 4

Structure of inner membrane mitochondria

Answer 4

Contains ATP synthase and respiratory chain.

Contains cristae
Contains f particles

Question 5

Matrix

Answer 5

Contains soluble enzymes that catalyse devradation of pyruvic acid and other molecules to c02 and after

Question 6

F particles have 3 regions. What are they?

Answer 6

Basal piece
Stall protein
Knoblike spheres that protrude the matrix

Question 7

ATP synthesising system

Answer 7

1) proton translocater
Embedded in the membrane

2) atp synthase
From inner membrane on matrix side
