Question

State whether the following statements are true or false.
Glycolysis and fermentation are thought to be older processes than the electron transport system and the Krebs cycle

• A. True
• B. False

Answer 1

The correct option is A True

The initial processes for energy generation by prokaryotes included anaerobic processes such as Glycolysis and Fermentation. The latter happening of endosymbiosis was the major revolution in bringing up aerobic respiration with the advent of mitochondria within the cells.

Before that, the energy generation was an anaerobic process without using oxygen in Glycolysis and Fermentation.

So, the correct option is 'True'.
