Question

There is a gain of ___ATP molecules during anaerobic respiration.

Answer 1

1. The steps of glycolysis continue to be identical until the formation of pyruvate for aerobic and anaerobic respiration.
2. After pyruvate formation, relying on the availability of oxygen the pyruvate could have exclusive fates in different organisms.
3. In animals, in which there is enough oxygen supply pyruvate enters the mitochondria and is completely oxidized to carbon dioxide.
4. Inside the absence of oxygen, it enters the anaerobic respiratory where it's far converted to lactate.
5. So, under aerobic conditions, the net formation of ATP until the formation of pyruvate is 2 ATP + (1 NADH = 3 ATP) = 5 ATP.
6. But, underneath anaerobic situations, the NADH isn't converted to ATP; therefore, the net production of ATP is handiest 2 ATP.
