Question

Choose the correct answers from the alternatives given :
Which process must occur before fermentation?

• A. Krebs cycle
• B. Glycolysis
• C. Electron transport system
• D. The transition reaction

Answer 1

The correct option is B Glycolysis

Fermentation is anaerobic respiration in which organic foods are degraded incompletely in the absence of oxygen.G glycolysis is the basic step of cellular respiration, it occurs in both aerobic as well as an anaerobic type of respiration. It is the common first step in both the type of respiration i.e; it must occur before the Krebs cycle as well as before fermentation.

So, the correct option is ' Glycolysis'.
