Correct option is C
The correct answer is (c).
During anaerobic respiration in skeletal muscle cells, the conversion of pyruvate to lactate is crucial for recycling NADH. In the absence of oxygen, cells cannot utilize the electron transport chain to regenerate NAD+, which is required for the continued operation of glycolysis. By converting pyruvate to lactate via lactate dehydrogenase, NADH is oxidized back to NAD+, allowing glycolysis to continue and ATP to be produced anaerobically. This process is vital for sustaining energy production during intense physical activity, where oxygen is limited.
Incorrect options-
Option (a) facilitate TCA cycle: Incorrect because the TCA cycle is aerobic and cannot proceed effectively without oxygen.
Option (b) maintain acidic extracellular environment: This is a consequence, not a reason for lactate production.
Option (d) generate more ATPs from NADH: Incorrect as ATP production from NADH occurs in mitochondria with oxygen, not through lactate formation.
