Respuesta :

Cellular respiration is the breaking down of food by the aid of oxygen in order to acquire chemical energy for the cell to function.

A. The three steps in celular respiration are the following: glycolysis, citric acid cycle, and electron transport.

B. Glycolysis produces 2 ATP. Citric acid cycle produces 2 ATP. Electron transport produces 30-32 ATP.

C. Glycolysis is the first step of cellular respiration. It is the breaking down of glucose to produce produce energy without the presence of oxygen. The output of this process are two molecules of pyruvate which were broken down from a glucose molecule.

D. The third step of cellular respiration is the electron transport. It is the transfer of electrons by way of oxidation-reduction reactions. It starts with the production of a proton gradient which are accumulated in the mitochondria. There is a formation of H2O molecule and the molecular oxygen is being reduced in the process. The last step is the production of ATP through the process of chemiosmosis. Electron transport involves NADH and FADH in the process. They act as electron transporters while flowing through the inner membrane of the cell.
