Parasitic nutrition is not a type of microbial nutrition, but rather a type of symbiotic relationship in which one organism (the parasite) benefits at the expense of another organism (the host).

Respiration is the process by which microorganisms obtain energy from organic compounds by breaking them down in the presence of oxygen.

Photorespiration is not a type of microbial respiration, but rather a process that occurs in plants to protect them from photodamage.

Photosynthesis is the process by which microorganisms convert inorganic compounds into organic compounds using energy from the sun.

Cyclic photophosphorylation is not a type of microbial photosynthesis, but rather a process that occurs in plants to generate ATP.

Chemosynthesis is the process by which microorganisms convert inorganic compounds into organic compounds using energy from chemical reactions.

Methane oxidation is not a type of microbial chemosynthesis, but rather a process that occurs in plants to generate ATP.

Glycolysis is the process by which microorganisms break down glucose into pyruvate.

Cleavage of fructose-1,6-bisphosphate into two molecules of glyceraldehyde-3-phosphate is not a step in glycolysis, but rather a step in the citric acid cycle.

The pyruvate dehydrogenase complex is the process by which microorganisms convert pyruvate into acetyl-CoA.

Generation of ATP is not a step in the pyruvate dehydrogenase complex, but rather a step in the citric acid cycle.

The citric acid cycle is the process by which microorganisms convert acetyl-CoA into carbon dioxide and water.

Decarboxylation of α-ketoglutarate to succinyl-CoA is not a step in the citric acid cycle, but rather a step in the glyoxylate cycle.

The succinate dehydrogenase complex is the process by which microorganisms convert succinyl-CoA into oxaloacetate.

Generation of ATP is not a step in the succinate dehydrogenase complex, but rather a step in the electron transport chain.
