Answer 1

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

The complete breakdown of glucose occurs in a series of steps in two pathways - glycolysis and the Krebs cycle, after which it must go through the electron transport chain. Various other molecules get broken down and enter these two pathways for further breakdown to give energy.

Solution Summary: The author explains that the Krebs cycle is the pathway in which metabolites are completely broken and a large amount of the energy in their chemical bonds is captured as ATP or used to reduce electron acceptors.
