Krebs cycle Flashcards
Where does the Krebs cycle take place
Mitochondrial matrix
What is the purpose of the krebs cycle
To oxidise acetyl coenzyme A
What is produced in the krebs cycle
ATP, reduced coenzymes including NAD and FAD, and CO2
How many turns of the krebs cycle are there for each molecule of glucose
2
What is the first stage of the krebs cycle
(2c) Acetyl group is released from acetyl coenzyme A
What happens to the (2c) acetyl group when it has been released from acetyl coenzyme A
It combines with (4c) oxaloacetate
What is formed as a result of (2c) acetyl combining with (4c) oxaloacetate
(6c) citrate
What happens to citrate
It is decarboxylated and dehydrogenated
What is produced as a result of citrate being decarboxylated and dehydrogenated
One molecule of CO2 and one molecule of reduced NAD and a 5 carbon compound.
What happens to the 5 carbon compound
It is decarboxylated and dehydrogenated
What is produced as a result of the 5 carbon compound being decarboxylated and dehydrogenated
One molecule of CO2 and one molecule of reduced NAD and a 4 carbon compound.
What happens to the 4 carbon compound
It temporarily combines with coenzyme A
What is produced when 4 carbon compound combines with coenzyme A
ATP is produced from ADP and Pi
What is it called when ATP is produced as a result of coenzyme A combining with 4 carbon compound
Substrate level phosphorylation
What happens to 4 carbon compound after it has combined with coenzyme A
It is dehydrogenated
