Question

ATP is produced during the process of cellular respiration. Which is the order of the steps of cellular respiration?

A. Krebs cycle, Calvin cycle, electron transport
B. electron transport, Krebs cycle, glycolysis
C. glycolysis, Krebs cycle, electron transport
D. Calvin cycle, electron transport, glycolysis

Answer 1

The answer is C. glycolysis, Krebs cycle, electron transport
Cellular respiration includes glycolysis, link reaction, Krebs cycle, and electron transport chain (ETC), in that order. The main function of ETC is a production of ATP. In this series of oxidation-reduction reactions, electrons from the previous stages of cellular respiration are taken and transported to the oxygen which is the final acceptor of electrons. As the result, water and ATP are produced.
