Write the equation for the link reaction.
Pyruvate + NAD + CoA –> acetyl CoA + reduced NAD + CO2
What is acetyl CoA?
It is the acetyl group binding with coenzyme A to produce acetylcoenzyme A.
Why are NAD and FAD important products of the Krebs cycle?
They have the potential to produce ATP
What are the products of the link and Krebs cycle from one molecule of pyruvate?
Reduced coenzymes like NAD and FAD
One molecule of ATP
Three molecules of carbon dioxide
Why is oxygen important in respiration?
Oxygen is the final acceptor of hydrogen atoms produced in glycolysis and the Krebs cycle in the electron transport chain. Without the oxygen hydrogen ions would not be accepted and would back up, halting the whole respiration process.
What is the equation of anaerobic respiration in plants? e.g: A waterlogged root hair cell.
Pyruvate + reduced NAD –> ethanol + CO2 + NAD
What is the equation of anaerobic respiration in animals?
Pyruvate + reduced NAD –> lactate + NAD
