Does glycolysis need o2
WebThe first step of aerobic respiration is glycolysis. This step takes place within the cytosol of the cell, and is actually anaerobic, meaning it does not need oxygen. During glycolysis, which means breakdown of glucose, glucose is separated into two ATP and two NADH molecules, which are used later in the process of aerobic respiration. WebAnswer (1 of 10): Yes, but it depends upon the organism. The amount of ATP produced by fermentation, or any other form of anaerobic respiration, is muct less than that produced by the aerobic respiration from the tricarboxylic acid cycle. If you stop and think about it, in fermentation one of th...
