Aerobic cellular respiration Utilizes glycolysis, synthesis of acetyl-CoA, Krebs cycle, and electron transport chain; results in complete breakdown of _________ to carbon dioxide, water & The ultimate objective is to make molecules to do cellular work. Each NADH results in 3 ATP, Each FADH2 results in 2 ATP. A total of 38 molecules of ATP are formed from one molecule of glucose. Lets figure out how we got 38 ATP by the end of aerobic respiration.

Using oxygen (1/2 O 2 ) in metabolism creates toxic waste. Microbes that are able to use aerobic respiration produce enzymes to detoxify oxygen: Catalase : H 2 O 2 ------- H 2 0 and 0 2 Superoxide dismutase (SOD): oxygen radical ----- H 2 0 and O 2 Microbes that don’t make these enzymes cannot exist in the presence of oxygen. Q: How do cells get energy if there is no O 2 available to them, or if they can’t use O 2 ? From the Virtual Microbiology Classroom on ScienceProfOnline.com

______ ______ ________ Image: Electron transport chain , Tim Vickers Cells that don’t have access to oxygen, or that are obligate anaerobes can make ATP by using something other than oxygen as an electron acceptor (nitrate, sulfate & carbon dioxide). In anaerobic respiration, not all the ETC is used, so less ATP is produced. From the Virtual Microbiology Classroom on ScienceProfOnline.com

______________ When there is no final __________ __________ for the ETC, the electron transport can’t happen. Fermentation is an alternative system that allows glycolysis to continue without the other steps of respiration. Not as energetically efficient as respiration. Produces only 2 ATP .

Metabolism & Identification of Microbes Some of the specialized media that we have worked with in lab is both selective and differential . The differential properties give us information about bacteria based on its metabolism. Qs: What is the medium in top picture? Is selective …Why? What does it grow? Is differential …Why? What does the differential property reveal about the bacteria growing there? Qs: What is the medium in bottom picture? Is selective …Why? What does it grow? Is differential …Why? What does the differential property reveal about the bacteria growing there ? Images: MacConkey’s Agar (MAC) & Mannitol Salt Agar (MSA), T.
