Glycolysis
|
Splitting a Glucose molecule into two three carbon pyruvic acid molecules
|
|
|
|
What type of process is glycolysis in terms of oxygen
|
Anaerobic
|
|
|
|
Where does glycolysis take place
|
In the cytoplasm of the cell
|
|
|
|
What does glycolysis consist of
|
A series of enzyme catalysed reactions
|
|
|
|
What does the glucose break down to
|
Two molecules of pyruvic acid
|
|
|
|
What is the net gain of ATP from Glycolysis
|
2 ATP
|
|
|
|
What is the hydrogen carrier in glycolysis
|
NAD > NADH2
|
|
|
|
What takes place inside the mitochondria
|
Respiration
|
|
|
|
When does the Krebs cycle occur
|
After glycolysis and in the presence of oxygen
|
|
|
|
What are the products of the Krebs cycle
|
NADH2 and CO2
|
|
|
|
What molecules occur in the cyclitic part of the Krebs cycle
|
coenzymeA, pyruvic acid, citric acid,
|
|
|
|
The cytochrome system does what
|
Releases energy in hydrogen that has been brought by NAD from Glycolysis and the Krebs cycle
|
|
|
|
What is the final hydrogen acceptor
|
Oxygen
|
It is at the end of the cytochrome system
|
|
|
How many molecules of ATP does the complete oxidation of one molecule of glucose make.
|
38
|
|
|
|
What does the term anaerobic mean
|
Without oxygen
|
|
|
|
What happens to respiration in an anaerobic environment.
|
Only Glycolysis occurs. The absence of oxygen means neither the Krebs cycle or the cytochrome system can operate
|
|
|
|
What does pyruvic acid from Glycolysis change into during anaerobic respiration
|
Plants: Ethanol and CO2
Animals: Lactic acid |
