Question

If skeletal muscles work to the point of fatigue, the muscle cells may not have sufficient oxygen to carry out aerobic respiration. What processes do muscle cells use if oxygen is not available for aerobic respiration? electron transport chain ethanol fermentation lactic acid fermentation glycolysis

Answer 1

Answer:

Lactic acid fermentation

Explanation:

Lactic acid fermentation is the process that is utilized by the cell to produce energy in the form of ATP. it is the process by which glucose and other six-carbon sugars and also some disaccharides are converted into energy and the metabolite lactate, which is lactic acid in solution.

Due to the absence of oxygen, this process converts 3-carbon pyruvate to the 3-carbon lactic acid in the cytoplasm producing NAD+, allowing glycolysis to continue to produce ATP in low-oxygen conditions. although accumulation of lactic acid can lead to cramps.

Answer 2

Lactic acid fermentation
