BRAINCAKELactate
Lactate produced during anaerobic respiration does not stay in the muscle. It diffuses into the blood and is carried to the liver.
In liver cells, lactate is oxidised back to pyruvate by lactate dehydrogenase, and NAD is reduced in the process. The pyruvate can then be:
• oxidised completely to carbon dioxide and water through the link reaction, Krebs cycle and oxidative phosphorylation, releasing the energy that was left in the lactate; or
• converted into glucose, which can be released into the blood or stored as glycogen.
