which of the thtee methods of analysis do you think gives the least accurate estimate? Give reasons for your answer [10marks] 1) v against [S] plot 2) lineweaver burk plot 3)...

from a lineweaver burk plot, I have calculated slopes of 12.42 and 1.38. The y intercept is 1.493 and 1.031 w/ respect to the slopes. Please include working out if possible...

Calculate the protein concentration for a sample with an absorbance at 280 nm of 0.5, giving your answer in units of mg protein/ml (NOTE: ε at 280 nm = 1 cm3 mg-1 cm-1 and a cuvette of 1cm path length...

Calculate the concentration of a sample of bovine serum albumin (Mr 67,000) with an absorbance at 280 nm of 0.5, giving your answer in units of M (Molarity) (NOTE: ε at 280 nm = 1 cm3 mg-1 cm-1 and...

Under conditions of saturating amounts of substrate the rate of formation of product is 50 nanomoles per ml of reaction volume every minute. [Hint: what do the words saturating amounts of substrate...

example would be Lysine. I know the standard form just having trouble grasping the concept. Thank you!

Why is it so that the Fe present in the haeme molecule of cytochrome cannot carry oxygen where as the one in haemoglobin can ?

1. The KM of an enzyme/substrate combination is 125 mM, with a VMAX of 20 μM.s-1. The concentration of enzyme is 45 nM. a. At what...

You are deciding which of two enzymes to buy for your Biotech company. Evaluated on the same substrate Enzyme A has a kcat of 950 s-1 and a KM of 200 μM, whereas Enzyme B has a kcat of...

According to the Michaelis Menten equation, at what percentage of its maximum rate is an enzyme operating when [S] = ½ KM?

Expressed as a multiple of its KM, how much substrate is required in order for an enzyme to be 50 % saturated? (i.e. what is [S]/KM?). And 98 % saturated?

I JUST NEED HELP

If 50 mL of 0.30 M propionic acid [PA] is added to 250 mL of 0.024 M NaOH, what is the resulting pH of the solution? pK = 4.87. I keep getting an answer of 4.47, but I know that it...

A young woman was at the gym doing great her normal workout. She would spend 45 minutes on the elliptical and then 15 minutes doing weight training. This was the regular routine for her as she...

Do unsaturated fatty acids with an odd number of carbon atoms in their chain exist in nature (for example C21:3)?

I first need to find the ph then i can use the Henderson hasslbach equation

1mL of Standard Glycine (7.5mg mL-1) was diluted into a 100mL volumetric flask. One standard had 0.30mL of the diluted standard glycine and 0.20mL of distilled water. How would I calculate...

How do I convert 0.075mg into μmol?
