Answer:
The correct answer would be glycolysis, Krebs cycle, electron transport.
Cellular respiration refers to the set of the chemical reaction taking place in a cell in order to convert the chemical energy of the food into adenosine triphosphate (ATP).
These chemical reactions can be majorly divided into three stages:
1. Glycolysis: It takes place in the cytoplasm of the cell. It converts one molecule of glucose (6C) into two molecules of pyruvate (3C) with a net gain of 2 ATP molecules and 2 NADH molecules.
The pyruvate is then transported into the mitochondria where rest of the reactions take place.
2. The pyruvate is converted into acetyl Co-A which then enters the Krebs cycle. The cycle undergoes two round to utilize 2 acetyl Co-A and produces 4 CO₂. It also produces 6 NADH, 2 FADH₂, and 2 ATP.
3 All the NADH and FADH₂ produced undergo electron transport chain and produces ATP with the help of oxidative phosphorylation.
