The Krebbs Cycle

The Krebbs Cycle 

Aerobic respiration 

Oxidaises acetyl coenzyme A 

Produces 

• CO2
• ATP
• Energy containing NADH, H+ and FADH2

It's a cycle/step process 

Required O2 termed aerobic cellular respiration 

Key Stages 

• Glycolysis 
• Pyrivate is formed 
• Oxidised Pyrivate 
• Acetyl coenzyme A is produced so it can enter the cycle 

At the end of the cycle, there are 4 carbon atoms

At the start of the…
