Pathway 1 Under aerobic conditions, pyruvate is first converted int.pdf
0 likes23 views
Under aerobic conditions, pyruvate is converted into acetyl-CoA, which enters the citric acid cycle, yielding about 14 ATP per pyruvate molecule. In anaerobic conditions, pyruvate undergoes fermentation depending on the organism and conditions, which does not produce ATP but regenerates NAD+ necessary for glycolysis. Thus, aerobic respiration is more efficient in ATP production compared to anaerobic fermentation.

Pathway 1 Under aerobic conditions, pyruvate is first converted int.pdf
- 1. Pathway 1: Under aerobic conditions, pyruvate is first converted into acetyl-CoA. The resultant acetyl-CoA enters citric acid cycle. Citric acid yields a net gain of around 14 ATP (2.5 ATP per NADH, and 1.5 ATP per FADH2) per pyruvate molecule. Pathways 2: Under anaerobic condition (example- lactate fermentation in skeletal muscles, ethanol fermentation in S. cereviseae, etc.), pyruvate enters fermentative pathways depending on the organism, and sometime, the cultural conditions. Fermentation of pyruvate does not produce ATP. However, it regenerates NAD+ required for glycolysis to keep going.
