Introduction:
Consumption of oxygen will change, according to the rate at which the pulmonary ventilation changes. Sprinting refers to running over a short distance in a limited period of time. Running is different from sprinting because in running long distances are covered.
(b)
To determine: The reason for high O2 demand after completion of sprint.

- You were tasked with purifying an untagged transcription factor (molecular weight 65,000Da, isoelectric point unknown) from a contaminant Protein A (molecular weight 50,000 Da, isoelectric point 5.0). You were also instructed to use the protein for crystallization studies after purification.i) In the initial purification step, which type of chromatography should you attempt? Explain your choice and specify the requirements of the buffer solution you should use. ii) Analyzing the proteins recovered from step i) using SDS-PAGE, you still observed a faint band of Protein A in addition to the transcription factor band. Given the limited time available for further purification, you must choose ONE appropriate chromatography method to maximize the chances of separating the two proteins as well as your crystallization studies. Provide a detailed explanation of your selection and the techniques/strategies you would employ to achieve this.arrow_forwardYou were given a mixture of two proteins with different isoelectric points and molecular weights:• Protein X: pI 4.2, MW 42,000• Protein Y: pI 9.8, MW 90,000Using a Tris-glycine discontinuous native gel (pH8.3) electrophoresis system with a running gel of 12%, only a single band was observed upon protein staining after electrophoresis. Explain the observed result and discuss possible factors affecting protein migration in this system.arrow_forwardThe standard cost of Product B manufactured by Oriole Company includes 3.5 units of direct materials at $5.40 per unit. During June, 27,300 units of direct materials are purchased at a cost of $5.15 per unit, and 27,300 units of direct materials are used to produce 7,600 units of Product B.
