- During an aerobic respiration practical. The citric acid is added to the test tubes. Why do we add it.I am having an incredible difficult time understanding how to do this. This is for Measuring gas bubbles in terms of Ceullar Respiration for yeast fermentation.in the fermentation by yeast experiment, if you observed respiration, identify the gas that was produced. Suggest two methods could used for positively identifying the gas
- Which of the following statements is false? A. Sulfur-oxidizing bacteria may form hydrogen sulfide (H2S) as a product of the oxidation. B. Dissimilatory reduction of metals such as Fe3+ to Fe2+ represents anaerobic respiration. C. The nitrification reactions carried out by certain bacteria would be considered lithotrophy. D. Denitrification reactions would be considered anaerobic respiration.The odors of sewage are mainly due to the products of the reductionanaerobic of organic compounds containing nitrogen and sulfur. Hydrogen sulfide (H2S) is an important component of sewage odors, but none of them way is the only producer of odors, since powerful odors can be perceived in its absence. Oxidation in air can be used to eliminate odors, but chlorine is the preferred treatment because it not only destroys H2S, and other odorous compounds, but also it also inhibits the bacteria that produce those compounds.As a specific example, hypochlorous acid (HCIO) reacts with H2S in Low pH as follows: ???? + ?2? → ? + ??? + ?2? If in actual practice an excess of 100% HClO is used (in order to ensure destruction total H2S, in view of the fact that HClO also reacts with other substances),a) What volume of dissolution at 5% by weight of HCIO should be added to 1 L of a aqueous solution containing 50 ppm of H2S, in milliliters (mL)? Note: Consider the density of the solution at 5% HClO…Some friends are trying to make wine in their basement. They've added yeast (which is a facultative anaerobe - it can perform both aerobic respiration and fermentation) to a sweet grape juice mixture and have allowed the yeast to grow. After several days they find that sugar levels in the grape juice have dropped, but there's no alcohol in the mixture. The most likely explanation is that the mixture needs less oxygen, because yeast only produce alcohol in the absence of oxygen the mixture needs less sugar, because high sugar concentrations prevent fermentation the mixture needs more sugar, because yeast need a lot of energy before they can begin to produce alcohol the yeast used the alcohol as a carbon source the mixture needs more oxygen, because yeast need oxygen to break down sugar and get enough energy to produce alcohol
- Ubiquinone and cytochrome c are both electron carriers that are easily diffused. Say whether it is true or false, if it is wrong to justify itThe figures below show the two different types of anaerobic respiration: alcoholic fermentation (left) and lactate fermentation (right). Read the descriptions in the table that follows, and then select whether each statement describes alcoholic fermentation, lactate fermentation, or both. Check all that apply. Generates two CO2 A. Lactate Fermentation B. Alcoholic FermentationComplete an enlargement of part of the thylakoid membrane in the beaker with the solution at pH 8. Label the areas of high H+ concentration and low H+ concentration. Show the reaction where ATP is synthesized. Drag the appropriate labels to their respective targets. Labels can be used once, more than once, or not at all.
- In aerobic respiration in bean experiment, what else could you incorporate into this experiment to verify that the gas is responsible for the color change?Pseudomonas aeruginosa is capable of aerobic respiration and anaerobic respiration but not fermentation. It can produce H2S, does not produce tryptophanase, and is motile by a flagellum. Based on the above characteristics, describe your expected results for Pseudomonasaeruginosa in a SIM deep.In the Cellular Respiration Lab Why is it necessary to absorb the carbon dioxide (CO2) in the vials? (What would happen to the water level if there was no KOH?)
