Outline how can chemical waste from oil industry generate income

NAD+ has negligible absorbable at 340nm. Using a name example, explain how you could use the change in absorbable properties between NADH (molar absorbable 6220M/cm) and NAD+ to measure the rate of a biochemical reaction.

Biological membranes are highly complex structures despite the mosaic of it's constituents. Explain how these chemically and physically diverse elements can form a coherent dynamic structure

180 µL of medium containing (200 µg/mL) Ampicillin were treated with 20 µL of ꞵ-lactamase enzyme to give finial concentrations ranging from 1:1 to 1:10 ratio of ampicillin to B-lactamase enzyme. The ꞵ-lactamase activity is 400 Unit/mg (Unit = 1 µmol / min hydrolysis of benzylpenicillin at pH 7 at 25C). The Ampicillin mass = 349.406 g/mol. Explain how to prepare the ꞵ-lactamase stock solution concentrations that can be used to give a final concentration ratio from 1:1 to 1:10 (ampicillin to enzyme) in the medium?
