7.2.7 - Anaerobic Respiration

Question 1

What Doesn’t Anaerobic Respiration Involve?
(2 Points)

Answer 1

~ Oxygen usage.

~ Link reaction, Krebs cycle or oxidative phosphorylation.

Question 2

Describe Lactate Fermentation
(3 Points)

Answer 2

~ Glucose -> Pyruvate, due to glycolysis.

~ Reduced NAD, transfers hydrogen to pyruvate, to form lactate + NAD.

~ NAD, can be reused in glycolysis.

Question 3

How Can Lactate Be Broken Down?
(2 Points)

Answer 3

~ Oxidised by pyruvate, re-entering the Krebs cycle, requiring extra oxygen, known as oxygen debt.

~ Converted into glucose, by liver cells for use during respiration or storage.
