Question

1. what is the correct sequence of stages in cellular respiration?

glycolysis, krebs cycle, electron transport chain
electron transport chain, krebs cycle, glycolysis
glycolysis, electron transport chain, krebs cycle
krebs cycle, electron transport chain, glycolysis

Explanation:

Cellular respiration begins with glycolysis which breaks down glucose. Then the Krebs cycle further processes the products of glycolysis. Finally, the electron - transport chain generates a large amount of ATP.

Answer:

A. glycolysis, Krebs cycle, electron transport chain
