There can be a net gain of 38 ATP molecules during aerobic respiration of one molecule of glucose. 3.Yeasts poison themselves to death when the concentration of alcohol reaches about 13 per cent. 4. The first process takes place in the matrix of the mit

Step-by-step solution

It is not possible to make calculations of the net gain of ATP for every glucose molecule oxidised. There can be a net gain of 38 ATP molecules during aerobic respiration of one molecule of glucose.,In animal cells also, like muscles during exercise, when oxygen is inadequate for cellular respiration pyruvic acid is reduced to lactic acid by lactate dehydrogenase. The reducing agent is NADH+H+ which is reoxidised to NAD+ in both the processes.
