Krebs Cycle W1 Flashcards
What is Krebs cycle?
Uses pyruvic acid to create ATP and electron carriers
How is pyruvic acid created?
Breakdown of food
What does the Krebs Cycle create?
ATP
Electron carrier molecules NADH and FADH2
What does the Krebs cycle do with pyruvic acid?
It changes it into citric by adding carbon and oxygen molecules
Where are the electron carriers produced?
The mitochondria
How many reactions occur in Krebs cycle to oxidise Acetyl CoA into CO2?
9
What produces the electron carriers?
Metabolites
What products does 1 glucose molecules produce?
2 pyruvate
2 Acetyl CoA molecules
How can be krebs cycle be upregulated?
Changes in key metabolites:
Decrease in ATP/ADP
Increase in Ca2+
How does Krebs cycle provide energy?
It converts Acetyl CoA into CO2
What enzyme regulates the rate-limiting step of Beta-Oxidation fats?
Beta-Hydroxyl Dehyrodgenase
