Whether the result of the experiment performed on the magnetite-producing bacteria support or undermines the hypothesis that the bacteria in the culture media perform cellular respiration . Introduction: The researchers observed the bacteria obtained from deep subsurface to produce magnetite under laboratory conditions. The same bacterial culture was treated with a poisonous drug, which blocked or inactivated the enzymes involved in the electron transport chains. These bacterial cultures did not produce magnetite.

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.
