Q

Transfers hydrogen from one side of the membrane to another

A

Hydrogen pump

17
Q

Space between inner and outer membranes of the mitochondria

A

Intercristae space

18
Q

Pump in the electron transport chain that catalyzes the transfer of the electrons to oxygen to make water.

A

Third pump

19
Q

Uses the energy of the hydrogen ion gradient to form ATP from ADP and phosphate

A

ATP synthase

20
Q

Importance of Cristae

A
  1. Contains ETC and ATP pump

2. Separates matrix from the space that will contain H+.

21
Q

Containing only inner membrane and matrix

A

Mitoplasts

22
Q

Technique that enables you to view the inside of the membrane surface of Mitoplasts

A

Negative staining

23
Q

Elementary particles in the inner surface of the Cristae

A

ATP synthase molecules

24
Q

Lies outside the inner membrane , a loosely attached peripheral protein in the space contained by the Cristae

A

Cytochrome C

25
How do mitochondria replicate
Undergoes fission like a bacterial cells
26
Mechanism of how mitochondria are being degraded
Autophagy, facilitated by lysosomes
27
Name of the yeast strain that has a structurally abnormal mitochondria that is incapable of oxidative phosphorylation.
Petite
28
Degeneration of optic nerve
Leber's herediatry optic neuropathy
29
Jerky movements
Ragged muscle fibers
30
Eye defects, abnormal heartbeat, central nervous system degeneration
Kaerns-sayre syndrome
31
A novel component of the mitochondrial nucleoid that binds DNA that is required for the repair of oxidatively damaged mtDNA
Mgm101p
32
An aqueous channel through which proteins can pass and go onto inter membrane space
Porins
33
The inner membrane contains this which renders it impermeable
Cardiolipin
