Answer 1

Answer:

a)

the process of anaerobic respiration in yeast cells is different from that occurring in human muscle cells. In yeast cells, ethanol is produced as a waste product of anaerobic respiration. In human muscle cells, lactic acid is produced as a waste product of anaerobic respiration.
