Calculate the volume of an object that has a mass of 26.2g and a density of 6.25gml

V = 4.192 cm3

Explanation:

m = 26.2g

d = 6.25g/mL = 6.25g/cm3

m = V × d

=> V = m/d = 26.2/6.25 = 4.192 cm3

-- the active site contains a serine residue, an unprotonated histidine, and an unprotonated aspartate residue at pH 7.0 prior to binding the substrate.

--  attack of a water molecule on the acyl-enzyme intermediate yields the second product.

-- an acetyl-enzyme intermediate forms during the mechanism.

Explanation:

p-Nitrophenyl acetate is a chemical compound and is used as a substrate in the assays for esterase as well as lipase activity.

Doing hydrolysis of the p-nitrophenyl acetate releases a p- nitrophenol, and its absorbance can be monitored at about 405 nm.

In doing hydrolysis of the p-nitrophenyl acetate by a chymotrypsin, the following holds true :

By hydrolysis, the acetyl enzyme intermediate is formed.an attack of the water molecule on acyl enzyme yields a second productthe site consists of a serine residue, unprotonated aspartate and an unprotonated histidine residue at pH
