Fermentation Life Without Oxygen- Definition


Fermentation is an anaerobic process which means life without oxygen. It is believed that fermentation and glycolysis occurred in earliest organism. It has evolved very early in the history of life, that time the earth’s atmosphere contained no oxygen. Fermentation can occur without oxygen.

The MCQs on “Fermentation Life Without Oxygen”, will help you to understand the evolution of fermentation, lactic acid fermentation and alcoholic fermentation. All the MCQs about Fermentation Process are published according to the new study syllabus for academic year 2021-22.

Table of Contents:

  • Evolution of fermentation
  • Lactic acid fermentation 
  • Alcoholic fermentation

All of these MCQs on “Fermentation Life Without Oxygen” in Zoology MCQs are preferably for test / interview preparation for BSc, MSc, BS (Hons), NTS, FPSC, PPSC, PTS, CSS, MDCAT, ECAT, MCAT and all other competitive examination for foreign study including overseas students.
