Document Summary

Hyper or super thermophiles: very high temperatures. Atp generated during glycolysis and by the oxidation of nadh and. Nad when pyruvate acts as the final electron acceptor. Organic compounds are the electron, energy, and carbon sources. Atp is generated during glycolysis and oxidative phosphorylation when inorganic compounds (other than o2) serve as the final electron acceptor. Inorganic compounds serve the energy and electron source. All-purpose media: allows from the growth of most bacteria (tsa and tsb) Differential media: growth of most bacteria but some bacteria have a characteristic appearance on the media. Selective media: allows only certain types of bacteria to grow and inhibits the. Positive result: bubbles when hydrogen peroxide is added. Negative result: no bubbles when hydrogen peroxide is added. Purpose: uses cytochrome oxidase in the etc. Special procedures: drop oxidase on cotton swab with bacterial smear on it. Purpose: determine if a bacteria can ferment a particular carbohydrate. Other components: peptone, beef extract, and durham tube.

How are aerobic respiration and anaerobic respirationsimilar?

	Both use oxygen as a terminal electron carrier.
	These are other names for glycolysis.
	Both utilize inorganic molecules as terminal electronacceptors.
	Neither receives electrons from glycolysis.
	Anaerobic respiration does not exist in microbes.
