CONTENT
◉fermentation (anaerobic respiration). Answer: the breakdown of
sugars without the use of oxygen, regenerate NAD+ so glycolysis can
continue
◉Glycolysis. Answer: the breakdown of glucose by enzymes,
releasing energy and pyruvic acid (2)
◉Krebs Cycle (Citric Acid Cycle). Answer: The Krebs Cycle, also
known as the citric acid cycle, takes place in the matrix of the
mitochondria. In the Krebs Cycle, each of the two acetyl coenzyme A
molecules enter the cycle and combine with oxaloacetate to form
citric acid, which then loses two carbons as carbon dioxide. The
cycle is now ready to begin again with the second Acetyl CoA. For
each Acetyl CoA, the Krebs Cycle produces 1 ATP, 3 NADH, and 1
FADH2.
◉Why is the krebs cycle general role in multiple metabolic
pathways?. Answer: Plays a central role in metabolism by
participating in protein metabolism, lipid metabolism, and
carbohydrate metabolism, as well as produing the majority of NADH
, ◉Electron Transport Chain (ETC). Answer: series of electron carrier
proteins that shuttle high-energy electrons during ATP-generating
reactions
◉The electron transport change produces the largest amount of
________________. Answer: ATP
◉A recently discovered new species of microorganism which does
not use oxygen in its metabolism was discovered growing in pH 10,
in hot springs, green in color and uses CO2 as source of carbon
nutrient rich soil. Describe in detail the nutritional and physical
requirements for this organism to grow, listing and explaining at
least five characteristics.. Answer: Does not use O2 - anaerobe
pH 10/lives in hot springs - alkalinophile
Lives in hot springs - thermophile
Green in color - photoautotroph/photoheterotroph
uses CO2 (inorganic) form of carbon - autotroph/phototroph
◉Compare and contrast the aerobic respiration and fermentation in
terms of pathways found in each, substrates, products, ATP amount
and their cellular location in microorganisms.. Answer: Aerobic
Respiration
1) Glycolysis
-Yields 2 ATP
