Question

Which connects glycolysis with the final stages of the aerobic pathways?

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

Answer 1

The correct option is D The transition reaction

Aerobic respiration is a type of respiration that requires oxygen. It has three processes :

1. Glycolysis is the first step of cellular respiration which occurs in both aerobic and anaerobic inside the cytoplasm. Here glucose breaks into pyruvate molecules.
   
2. Krebs cycle is the final stages of respiration, here pyruvate enters the inner mitochondrial membrane than to the mitochondria and gets under oxidative decarboxylation to produce acetate. this starting step of formation of acetyl CoA is termed as link reaction as it is the connecting link between the initial and final stages of aerobic respiration, this is also called as transition reaction.
3. An electron transport system is the series of a passage of electrons through carriers, it occurs after the Krebs cycle.

So, the correct option is ' The transition state'.
