Question

how many atp molecules are produced (net) as a result of glycolysis and lactic acid fermentation?
4
32
1
2
36

Explanation:

Glycolysis produces 4 ATP molecules, but 2 ATP molecules are used in the initial steps of glycolysis. So the net ATP from glycolysis is \(4 - 2=2\). Lactic acid fermentation does not produce additional ATP; its role is to regenerate NAD+ for glycolysis to continue.

Answer:
