Question

Choose the correct answers from the alternatives given :
Which of these processes occurs in the cytosol?

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

Answer 1

The correct option is B Glycolysis

The process of cellular respiration occurs into three steps :

1. Glycolysis
2. Krebs cycle
3. Terminal oxidation

Glycolysis is the basic step of respiration where glucose is broken down into two molecules of pyruvate which occurs in the cytoplasm and does not require oxygen while other processes like Krebs cycle, electron transport system and transition reaction occurs in the mitochondria of the cell.

So, the correct option is ' Glycolysis'.
