Which of the following cellular metabolic processes can occur both in the presence or absence of `O_(2)`?

Options

A. Glycolysis
B. Fermentation
C. TCA cycle
D. Electron transport coupled with chemiosmosis

Answer

a

Explanation

Glycolysis is an oxidative process in which one molecule of glucose partially oxidised into two molecules of pyruvate on a series of enzyme catalysed reactions. Glycolysis, the major pathway for glucose metabolism, occurs in the cytosol of all cells. It is a unique pathway that occurs aerobically as well as anaerobically and does not involve molecular oxygen.
