- Yeast are facultative anaerobic organisms that can make ATP by aerobic respiration if oxygen is present, but are also capable of switching to fermentation under anaerobic conditions. For thousands of years, humans have used yeast, such as Saccharomyces cervesisiae, to ferment grapes (starch sugar) to make wine (alcoholic beverage). Four batches of wine were made following the contents and conditions listed in the table below, Contents and Conditions of Four Batches of Wine Yeast Solution Water Grape Solution Batch Added Container (L) (L) (L) Lid 1 40 0.0 8 оpen 2 40 0.2 8 closed 40 0.2 8. оpen 4 40 0.2 closed 9. The yeast (Saccharomyces cerevisiae) would produce the greatest amount of ATP is the batch of wine numbered 1 4 D. The highest alcohol (ethanol) content would be found in the batch of wine numbered 02 3Compare and contrast fermentation, aerobic respiration, and anaerobic respiration inBACTERIA. Be sure to include discussion of electron donors and acceptors, mechanismof ATP generation, where each step occurs, and amount of energy (ATP) produced.The main goal of fermentation is to regenerate NAD+ to sustain ATP production by glycolysis.

- coliis a species of bacteria that, under the appropriate conditions, can grow using fermentation, anaerobic respiration, or aerobic respiration. This is one example of how E. colihas a greater metabolic capability than we humans, who can only survive using aerobic respiration, and who can perform fermentation for short periods of time. Consider the relative energy yield and efficiency of these three processes. Imagine you grow three cultures of E. coli as follows: A: Fermentation B: Anaerobic respiration C: Aerobic respiration You provide each culture with sufficient glucose in order to get each culture to produce the same biomass, i.e., the same amount of E. coli cells. In order to accomplish this, which culture would need to consume the greatest amount of glucose? Group of answer choices A. Each culture would need to consume the same amount of glucose to produce the same biomass B: Aerobic respiration C: Anaerobic respiration D: Fermentationa. Some microbes can utilize fermentation to make ATP. Compare and contrast fermentation and aerobic respiration, including the typical inputs and outputs of each. b. Two liquid culture flasks of E. coli are grown in the same medium (2% glucose and amino acids) and at the same temperature (37°C). Culture #1 is well aerated. Culture #2 is anoxic. After 16 hours, the following observations are made: • Culture # 1 has a high cell density; the cells appear to be in stationary phase, and the glucose level in the medium is reduced to 1.2%. • Culture #2 has a low cell density; the cells appear to be in logarithmic phase, although their doubling time is prolonged (over 1 hour). The glucose level is reduced to 0.2%. Why does Culture #2 have so little glucose remaining relative to Culture #1, even though Culture #2 displayed slower growth and has less biomass?waste product of anaerobic respiration by animal cells seous product of the Krebs cycle udent set up the apparatus shown below, one with germinating seeds and one with dry seeds.

- The photosynthetic process used by the green sulfur bacteria, under anaerobic conditions, is best represented by which of the following balanced equations? cell bio 6CO2 + 12H2S C6H12O6 + 6S2 + 6H2O C6H12O6 + C6H12O6 C12H22O11 + H2O 6CO2 + 12H2O C6H12O6 + 6O2 + 6H2O C12H22O11 + H2O C6H12O6 + C6H12O6 C6H12O6 + 6O2 + 6H2O 6CO2 + 12H2OIn aerobic respiration, cells generate heat as they grow. The amount of heat generated by cells is proportional to the amount of oxygen they consume. Accordingly, it was found that 460 kJ is generated per gmol of O2 consumed. Suppose that you need to choose a fermenter for optimal growth of Bacillus subtilis cells. It is known that the maximum oxygen demand of B. subtilis is 100 mol m3 h1. A vendor offers you a reactor with a cylindrical shape (2.8 m in diameter) and 15 m³ volume. The reactor includes a cooling coil with 30 m length and a pipe diameter of 6 cm, through which. For practical purposes, power input by the rotating impeller inside the bioreactor can be neglected. Does this reactor meet the cooling requirements of your production process?

In this case, please state your source clearly. Note: You may assume that the…a. Name a metabolic type that might be found in Section 3 of the column. List the energy source and the compounds the organism would use as carbon and electron sources. b. You isolated a bacterium from Section 2 of the column. You hypothesize that this bacterium might ferment xylem, a common carbon source found in plants. What carbohydrate test would you use to test your hypothesis? Be specific about any compound(s) that would need to be in the test. If the bacterium could ferment xylem, what result would you expect?
- 1. You set up two cultures with an equal amounts of Escherichia coli. You label one culture "A" and the other "B." Each culture is given 100mL of tryptic soy nutrient broth. You then take culture A and incubate it in the absence of oxygen and take culture B and incubate it in the presence of oxygen for one week. If E. coli is able to use both aerobic and anaerobic metabolism, the how would we classify it? Is it an obligate aerobe, obligate anaerobe, or a facultative anaerobe? Based on that information, which flask, A or B, would have more cells at the end of the week?
