Question

when in the presence of sugar,yeast perform which process a. an aerobic process that occurs in cytoplasm b. an aerobic process that produces alcohol c. an anarobic process that produces lactic acid d. an anearobic processthat has co2 as a byproduct

Answer 1

d.
reason : yeast fermentation does not involve oxygen and ethanol is produced not lactic acid, hence it is anaerobic

Answer 2

In the presence of sugar, yeast perform an anearobic process that has co2 as a by product. An anearobic process is one chemical process that does not require oxygen in order to perform. Sugar and yeast combine together do not perform a process that requires oxygen, thus the process cannot be aerobic and must be anaearobic.
