Question:

Fate of pyruvate produced by glycolysis depends on cellular needs, it can enter

Options:

1. Lactic acid fermentation
2. Alcoholic fermentation
3. Aerobic respiration
4. All are correct

Solution:

The fate of pyruvate produced by glycolysis depends on cellular needs, and it can enter all three pathways mentioned in options 1, 2 and 3. Under anaerobic conditions, pyruvate can undergo lactic acid fermentation in certain organisms such as bacteria, fungi, and animal muscle cells, producing lactate as a byproduct. In yeast and some bacteria, pyruvate can undergo alcoholic fermentation, producing ethanol and carbon dioxide as byproducts. Under aerobic conditions, pyruvate enters the mitochondria and undergoes oxidative decarboxylation to form Acetyl-CoA, which then enters the citric acid cycle (Krebs cycle) to produce ATP through oxidative phosphorylation.
