In this experiment, 4 different organisms (A, B, C and D) were streaked on two nutrient agar plates and incubated at different oxygen conditions. One plate was incubated aerobically (on the counter top) and 1 plate incubated anaerobically in a sealed Gas-pak jar. Read the results below and answer questions.

We considered the effects of many parameters in designing bioreactors. Please answer the following questions regarding bubbles in airlift fermenters. Bulleted lists are okay. (a) Why was it undesirable to use a very large bubble size (Diameter >7 mm)? (b) Why was it undesirable to use a very small bubble size (Diameter <7 mm)? (c) Other than varying bubble size, what can be done to further decrease cell death due to entrainment?
after a 5 g onion sample is divided into two equal parts, heat treatment to one of these partsit is being implemented. Then both heat-treated and non-treated parts are 10 times their weightit is ground in an environment containing as much buffer and the determination of pyruvate in the supernatants obtainedit's being done.a) As a result of measurements taken at 520 nm; absorbance value for the heat-treated sample;it was found that the absorbance value in the sample that was not heat treated was 0.123 and the absorbance value in the sample that was not heat treated was 0.520.The equation of the calibration accuracy for pyruvate is that y = 0.1367x – 0.001 (nmol/mL)according to the onion sample; a) independent of alinase activity; b) dependent on alinase activityand c) calculate the total pyruvate amounts in terms of nmol/g of onion.b) How is there a relationship between the activity of the enzyme allinase in onions and the amount of pyruvate?Dec,please explain.
Using a P-1000 micropipette, you transfer 800 microliter of ddH2O to a beaker and measure its weight. It turns out to be only 780 milligram; what is the percent error of this micropipette?
What is the purpose of the respirometer with just rocks (the thermobar)? What conditions would cause movement of the water bubble in the pipette of this respirometer during the experiment?
Introduction Cellular respiration (sometimes called aerobic respiration) occurs in all animal and plant organisms (with a few exceptions). This is the process where food substances such as glucose are metabolised (using oxygen) to produce carbon dioxide and energy. It basically consists of three parts ie glycolysis, Krebs' cycle and oxidative phosphorylation linked to electron transport and chemiosmosis. At the end of the process large amounts of energy in the form of ATP are produced, for cell metabolism and growth. Part 1. Experiments on cellular respiration. Experiment 1 In an investigation of aerobic respiration was carried out using isolated mitochondria. Were added to a prepared medium containing succinate and inorganic phosphate. Note: The mitochondria were isolated from liver cells by the following method: 1. The liver tissue was ground with sand in a pestle and mortar, containing a phosphate buffer at pH 7.0, and 0.4 % sucrose solution, at 4°C. 2. The homogenate was spun…
Absorbance is directly proportional to glucose concentration for both routine clinical glucose spectrophotometry methods: glucose oxidase method and the hexokinase method. For each one, name the final product measured in each test reaction, which is proportional to the sample glucose concentration. A.) glucose oxidase: B.) hexokinase:
You set up the following two tubes: Tube 1: 1mL of alkaline phosphatase + 4mL of 400 µM p-NPP Tube 2: 1mL of alkaline phosphatase + 4mL of 200 µM p-NPP Which tube would have a faster reaction rate? Explain your reasoning (why does concentration of p-NPP matter? Relate it back to week 4 lab concepts). Week 4 lab concepts: - concentration gradient - differentially permeable membrane - solute, solvent, diffusion, osmosis, hypotonic, isotonic, hypertonic, molarity, osmolarity

When the yeast cells have completely re-hydrated, measure out 1.8 mL of well-mixed yeast suspension (0.2% yeast) into each of two new 15 mL centrifuge tubes. Add 200 μL of a 10% (w/v) Sodium Azide*** in YGM solution to one of the 15 mL tubes with yeast suspension. Add 200 μl of YGM to the other 15 mL tube of yeast suspension for your Control. Let both tubes incubate at room temperature for 30 min, vortexing every ~5 minutes What is the % concentration of azide in this sample during metabolic inhibition?What is the % concentration of yeast in this sample during metabolic inhibition?
