Giovanni Norris · Answer 1

More ATP is produced in mitochondria

Explanation:

Glycolysis is the first stage of cellular respiration. It is a common process of both anaerobic and aerobic respiration. It occurs in the cytoplasm of a living cell. During glycolysis 4 ATP and 2 NADH is produced and 2 ATP is used up. Thus, there is net gain of 2 ATP. The completion of cellular respiration takes place in mitochondrial matrix and on inner membrane, where all the co-enzymes NADH and FADH₂ oxidised to release ATPs. On oxidation each NADH produce 3ATP and each FADH₂ produces 2 ATP. Total 10 NADH is produced during complete oxudation which yield 30 ATP and 2 FADH₂ yields 4 ATP. Thus, in the mitochondria more ATP is produced as compared to glycolysis.

Anabella Mills · Answer 2

In eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH. Jun 26, 2001
