Mitochondria Flashcards
What form is Mitrochondria’s genome in?
Circular genome.
Do mitochondria produce their own proteins?
Yes.
Name the 4 phases of cellular respiration.
Glycolysis
Oxidation of pryruvate to Aceyl CoA
Citric Acid Cycle
Chemiosmosis and oxidative phosphorylation
Where does glycolysis occur?
In the cytoplasm
What does glycolysis produce?
4ATP, 2NADH+, 2H2O, pyruvate.
What is glycolysis split into?
The energy investment phase and the energy pay off phase.
In an anaerobic environment what does glycolysis produce?
Lactic acid and ethanol in yeast.
What is the name for the enzyme responsible for the formation of Acetyl CoA?
Pyruvate decarbolyase
Where does the citric acid cycle take place?
In the matrix of the mitochondria.
What are the products of he citric acid cycle?
8 NADH+, 2FADH2, 2CO2, 6ATP
What does chemiosmosis do?
It pumps H+ ions down their conc gradient through ATPases, synthesising ATP.
What are NADH and FADH2 passed through in the last stage of cellular respiration?
FE containing proteins.
Where do H+ ions get pumped to In chemiosmosis?
From the matrix of the mitochondria to the intermembrane space
Where does chemiosmosis take place?
The inner membrane of the mitochondria
How is a PMF (proton motif force) created?
By pumping ions across a membrane, i.e. The unequal distribution of ions across a membrane.
