Calculate the percentage efficiency of extraction of phycocyanin in sample y, if the amount of phycocyanin is 57.8 mg, and the starting amount in sample x was 118.1 mg. Your answer should have one decimal place.
A purified protein fraction has a total sample volume of 450 µL. The sample has a corrected A280 of 0.244, and the blank corrected A280 was 0.077. (Both values were measured with a path length of 1.00 cm.) If 5.50 µL of the sample was used in a reaction, calculate the mass of protein in the reaction (in µg).
The fosfomycin disc (200/50) also contains glucose-6-phosphate (G-6-P). Which ONE of the following best describes why this is the case? Select one: A. G-6-P increases the solubility of fosfomycin B. G-6-P is used to promote active transport of fosfomycin into the bacterial cell C. G-6-P is used in the formulation to correct glucose deficiencies promoted by fosfomycin D. G-6-P stabilises fosfomycin from spontaneous hydrolysis in aqueous solution E. G-6-P is an inhibitor of FosA that inactivates fosfomycin
Please answer with explanation. I will really upvote
please help me identify these huhu thank you
If protein X produces a higher absorbance reading at pH 7 than it does at pH 9, what can you conclude? Question 1 options: A lesser amount of protein X was used in the reaction at pH 7 than at pH 9. A greater amount of protein X was used in the reaction at pH 9 than at pH 7. Protein X is a more efficient catalyst at pH 7 than it is at pH 9. Protein X is a more efficient catalyst at pH 9 than it is at pH 7.
A purified protein fraction has a total sample volume of 360 µL. The sample has a corrected A280 of 0.484, and the blank corrected A280 was 0.052. (Both values were measured with a path length of 1.00 cm.) If 5.00 µL of the sample was used in a reaction, calculate the mass of protein in the reaction (in µg).
